  • Integral Equations and Method of Moments

    This chapter discusses the method for determining the current distribution along a straight conductor. It explores the integral equation for an arbitrarily shaped wire antenna for the unknown current along the wire using the Method of Moments (MoM). The unknown current in integral equation is often solved using a point¿¿¿matching technique, which is a MoM technique. The integral equation becomes a powerful analysis tool for an antenna whose shape is expressed by a simple function and, hence, the integrals and derivatives in the kernel, are readily manipulated. However, if the antenna has a complicated structure, the kernel calculations require cumbersome manipulations. To simplify the programming of the solver and reduce the computing time, it is desirable to derive an integral equation with a closed¿¿¿form kernel. Such an integral equation has been derived.

  • Radio Propagation

    Radio wave propagation is a key topic for an in‐building wireless system designer, and has its foundations in electromagnetic theory principles. The existence of propagating electromagnetic waves can be predicted as a direct consequence of Maxwell's equations. Maxwell's curl equations contain constants of proportionality, which dictate the strengths of the fields. In free space, many types of waves can exist, which satisfy Maxwell's equations; that is constitute valid solutions. Amongst the most popular ones are spherical, cylindrical and plane waves. Maxwell's curl equations also dictate special behaviour when impinging on a material. The chapter discusses the median path loss, fast fading, shadowing (slow fading) and building penetration loss. A deep understanding of the propagation mechanisms that affect link performance is thus essential if path loss and/or signal strength is to be predicted inside buildings with reasonable accuracy.

  • PEEC Models for Dielectrics

    This chapter concentrates on inclusion of several different dielectric circuit¿¿¿oriented models in partial element equivalent circuit (PEEC) to cover a wide range of applications. The interesting aspect is that once either the real or imaginary part of the dielectric model is known for the entire frequency range 0 ¿¿¿ f ¿¿¿ ¿¿¿, then the other part is uniquely determined by the so¿¿¿called Hilbert transform. The chapter describes three different issues. First, the chapter treats the electrical description of dielectric materials in the time and frequency domains. Second, the chapter considers different approaches for the description of the properties of dielectrics such that they can be included in the PEEC solution. Third, it presents approaches for the inclusion of dielectrics in a PEEC model. The chapter further presents equivalent circuits for the multi¿¿¿pole Debye model, the Lorentz model, and other general combined models.

  • Applications of Parallel¿¿¿coupled Microstrip Lines

    This chapter deals with the detailed design of parallel¿¿¿coupled microstrip structures. The main design element considered in the chapter is the design of a directional coupler. Many of the techniques used in designing circuits with coupled transmission lines are introduced, in particular design of coupled lines beginning with an electrical design, such as the required even and odd¿¿¿mode characteristic impedances, and then realizing the electrical design in physical form. The chapter discusses some special coupler designs with improved performance such as the Lange coupler, shielded parallel¿¿¿coupled microstrips, couplers using dielectric overlay and incorporating lumped capacitors. Thickness effects play only a small part in the accurate design of coupled lines, provided the lines are of thick¿¿¿ or thin¿¿¿film manufacture and the coupling is around ¿¿¿10 dB. The fundamental nature of microstrip line structure is important in relatively simple couplers and significant in circuit applications such as parallel¿¿¿coupled bandpass filters.

  • 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.

  • Microstrip Design at Low Frequencies

    Microstrip is a particularly useful transmission line medium for implementation in distributed circuit designs at frequencies from below 1 GHz and up to 110 GHz. This chapter deals with some fundamental aspects of the microstrip structure, and the realization of dimensional design parameters for establishing desired electrical characteristics. It is concerned with basic considerations and microstrip synthesis where the substrate is a homogeneous, isotropic dielectric. The aspects discussed are quasi¿¿¿transverse electromagnetic mode (TEM) of propagation, static¿¿¿TEM parameter effective microstrip permittivity, characteristic impedance, and filling factor. Graphical technique is mainly suitable for approximate guidance purposes. Hence, closed formulas are needed for accurate static¿¿¿TEM design calculations. The chapter considers microstrip synthesis using a dielectrically anisotropic substrate. It discusses the effects of finite thickness and manufacturing tolerances, and provides a description of pulse propagation. Finally, recommendations for microstrip design are presented.

  • Waves in Metamaterials and Plasmon

    This chapter discusses some of the fundamentals of metamaterials including transformation electromagnetics (EM) and cloaking. Most encountered materials in practice have relative permittivity greater than one, except plasma whose relative permittivity is less than one, and relative permeability equal to one, except magnetic materials. Artificial magnetic materials have magnetic properties not found in nature even though the materials are nonmagnetic. Split‐ring resonators (SRRs) are a typical example. A man‐made chiral material consisting of a collection of metal helices is another example. The chapter also discusses another example that is bianisotropic media. SRR has been studied for use in magnetic resonance. Its size can be small and can be used as a homogeneous medium. The chapter further discusses a new and different application of the coordinate transformation, not for producing a new material, but for using the transformation to solve a wave scattering problem. Finally, it considers a wave propagating over a rough surface.
