  • 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.

  • Electromagnetic Wave Propagation

    This chapter contains sections titled: Properties of Plane Electromagnetic Wave Radiant Continuous Aperture General Characteristics of Antennas Free‐Space Loss and Electromagnetic Field Strength Reflector and Passive Repeater Model of Propagation Reflection and Refraction Influence of Atmosphere Propagation by Diffraction Attenuation by Atmospheric Gases Attenuation and Depolarization by Hydrometeors Influence of Ionosphere Thermal Radiation Probability Distributions

  • Fundamentals of Electromagnetic Scattering

    This chapter reviews the fundamental field equations and provides necessary information on boundary conditions and material relations that are used to model electromagnetic properties of materials. It describes the basic field solutions in the form of plane, cylindrical, and spherical waves, the tensor Green function of the vector wave equation, separation of fields in E and H modes, and introduces the electromagnetic form of the Huygens principle. The chapter begins by specializing Maxwell's equations to the case of homogeneous isotropic source‐free medium and noting that their solutions are waves with different propagation directions. The chapter shows that the combination of Maxwell's equations with all these conditions ensures the uniqueness of the solution of the time‐harmonic scattering problems. It presents some of the basic solutions and solution methods that are of particular importance for the electromagnetic scattering theory.

  • The 2D Scattering Equations for Dielectric Targets

    The behavior of the electromagnetic signal radiated by a ground-penetrating radar (GPR) and scattered by buried targets is governed by Maxwell's equations. So, in order to provide hopefully deep enough and self-consistent discussion of GPR data processing, this chapter starts from the beginning and provides the derivation of the whole formulation up to the migration and the linear inversion. This chapter describes the derivation of the scattering equations without considering the effect of the antennas, and the calculation of the incident field radiated by a filamentary current. It discusses plane wave spectrum and effective length of an electromagnetic source in a homogeneous space. The chapter considers the problem of inserting the source and receiver characteristics into the scattering operator. It calculates the far field in a homogeneous lossless space in terms of plane wave spectrum.

  • 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.

  • 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.
