  • Porous Media, Permittivity, Fluid Permeability of Shales and Seismic Coda

    This chapter discusses the characteristics of porous media and seismic coda waves. One of the important examples of a porous medium is oil shale. One is the permittivity and conductivity of the porous medium as given by Archie's law. The other is the flow of liquid such as oil through the porous medium as given by Darcy's law and "fluid" permeability, which is different from the "magnetic" permeability concept we commonly use in electromagnetic studies. The study of porous media is closely related to the "percolation theory" and the "fractal". The permeability of a porous medium such as shale is a measure of the resistance to the flow of a fluid through the medium. The chapter shows typical seismic waves observed at the receiver. The study of the P‐coda, S‐coda, and Rayleigh‐coda is critical to the understanding of the total seismic radiation.

  • Propagation at THz Frequencies

    In this chapter we first briefly introduce Maxwell's equations and derive the Helmholtz equation, a special case of the wave equation, and introduce its different solutions for fields that may propagate in THz waveguides. The second section describes different waveguides operating at THz frequencies. The third section is devoted to the beam waveguide and quasi-optics. Material issues related to waveguides and quasi-optical components are also discussed. The chapter concludes with THz wave propagation in free space.

  • Magnetic Material Modeling

    This chapter introduces some shape preserving interpolation (including extrapolation) schemes. It shows that the derivative of the linear interpolant discontinues at each sampling point, which may cause the Newton‐Raphson iteration in finite element analysis (FEA) not to converge to a smaller error. The quadratic spline interpolation is also based on the pre‐selected discrete derivative set. Anisotropic behavior is often encountered not only in the grain oriented but also in the laminated grain non‐oriented magnetic cores in electromagnetic devices. The chapter presents case study of a 400 W 4‐pole synchronous reluctance motor with axially laminated anisotropic rotors. Permanent magnet (PM) machines are usually designed with reasonable demagnetization in normal working conditions. In some occasional cases, a PM motor may operate at an overloaded torque. The chapter presents an algorithm to construct demagnetization curves for magnetization.

  • Background Theory

    This chapter provides some background theory and introduces notation in preparation for use throughout the remainder of this text. The equations that were devised by James Clerk Maxwell and placed in differential form by Oliver Heaviside and Heinrich Hertz are introduced. Heaviside, and independently Hertz, reduced these 20 equations to the four vector field equations that are essentially used today. For Heaviside, the concepts of fields, symmetry and vector notation were vital. The partial field pairs, satisfy separate sets of Maxwell's equations. The time‐averaged conservation of energy in the electromagnetic field is given by Poynting's theorem. The chapter also summarizes the important concepts of field duality, equivalent sources and image theory. Finally, radiation from elementary sources is investigated, and this allows a description of some basic radiation parameters as well as an introduction to mutual coupling.

  • Magnetic Mirror Model

    Improved magnetic mirror models (IM3) for mono and dual coils with a finite width and infinite permeability are explained in this chapter [47]. By introducing a mirror current, which is located at the same distance from a source current but with a smaller magnitude than the source current, the magnetic flux density of the mono and dual coils can be determined in a closed form. The ratio of the mirror current and source current is identified as a function of the width of the core plate and the distance between the source current and core plate, as rigorously derived from the finite¿¿¿element method (FEM) simulations. Applying the proposed IM3 to the mono and dual coils used for wireless electric vehicles, the magnetic flux density over an open core plate is analyzed and its maximum points on the plate are found, which is crucial in the design of the coils to avoid local magnetic saturation. Furthermore, the magnetic flux density when a pick¿¿¿up core plate is positioned over a primary core plate is also analyzed by introducing successive mirror currents. The proposed magnetic mirror models are extensively verified by experiments as well as site tests, showing quite promising practical usefulness.This chapter is based on the paper by W.Y. Lee, J. Huh, S.Y. Choi, X.V. Thai, J.H. Kim, E.A. Al¿¿¿Ammar, M.A. El¿¿¿Kady, and C.T. Rim, ¿¿¿Finite¿¿¿width magnetic mirror models of mono and dual coils for wireless electric vehicles,¿¿¿ _IEEE Trans. on Power Electronics_, vol. 28, no. 3, pp. 1413¿¿¿1428, March 2013.

  • Magnetic Circuits and Transformers

    This chapter contains basic concepts that can be used for all rotating machines and for power transformers. It presents a more complete analysis and more detailed circuit models of real-life transformers. When the transformer operates in sinusoidal steady state, the corresponding phasor circuit can be used to analyse it. Three-phase transformers can have different construction modes. The chapter briefly presents only the transformers created as a three- phase bank of single-phase transformers. Magnetic hysteresis is important also from an energy point of view: it can be demonstrated that hysteresis phenomenon implies loss of energy in the magnetic circuit of the transformer, which reduces efficiency and heats the iron.

  • Magnetic Actuators Operated by DC

    Magnetic actuators use magnetic fields to transform electrical energy into mechanical energy. Thus they are a type of transducer. This chapter discusses in detail the most common types of magnetic actuators operated by direct current (DC). The magnetic actuators discussed in the chapter are: solenoid actuators, voice coil actuators, other linear actuators using coils and permanent magnets, proportional actuators, rotary actuators, magnetic bearings and couplings, and magnetic separators.

  • Fem‐Based Analysis Techniques for Electrical Machine Design

    The Newton‐Raphson technique for the solution of nonlinear problems in finite element analysis (FEA) has been widely accepted due to its quadratic convergence characteristics. This chapter introduces an indirect approach with parameter coupling. It also introduces an efficient method, referred to as alternating flux linkage (AF) model, to speed up the transient process for reaching fast AC steady state, almost suitable for all AC machines. Transient electromagnetic field simulation allows analysis of dynamic behaviors with nonlinear materials, permanent magnets, and induced eddy currents under various excitations. The basic procedure of transient simulation includes the spatial and temporal discretization of the physical equations. The finite element method (FEM) is widely used in engineering practice because using the irregular grids it can represent complicated geometry. The chapter explores some advanced algorithms to create look‐uptable based ROMs, and some efficient techniques to reduce computational time at specified density of the sampling points.

  • Reluctance Method

    The reluctance method is a way of using Ampere's law to solve for magnetic fluxes and magnetic fields. For very simple problems, its results are often reasonably accurate, and thus it often serves as a first step in the process of designing magnetic actuators and sensors. This chapter highlights the steps involved in reluctance method, and provides examples for the method for a ?>C?> steel path with airgap and for a sensor with variable airgap. The chapter provides a brief discussion on the concepts of fringing flux and complex reluctance, and is concluded by highlighting the limitations of reluctance method.
