Electromagnetic Sources and Electromagnetic Fields (Modern Antenna)
by Gaobiao XiaoThis book presents a modified spherical harmonic expansion method in which the electromagnetic fields and their sources are expanded with the same set of spherical vector basis functions in a similar procedure. Explicit expressions for the electromagnetic fields, potentials, energies, and the related Green’s functions are derived for the spherical modes in both frequency domain and time domain. Based on the formulation, the relationships between the electromagnetic sources, the electromagnetic far fields, and the electromagnetic near fields are clearly revealed. In particular, a nonuniform transmission line model is developed for intuitively characterizing the total radiation process. The introduction of the cutoff radius and the cutoff mode degree provides a simple reference for determining the numbers of degrees of freedom of the fields associated with sources in a bounded region. Based on the theory, an efficient hybrid method for synthesizing antenna arrays with complex footprints is proposed and demonstrated with several numerical examples. Effective algorithms are also developed for reconstructing the radiating part of the current sources.This book is intended for researchers, engineers, and graduate students who are interested in studying the energy transfer in electromagnetic radiation, synthesis and measurement of antenna arrays, and applications of inverse electromagnetic source problems.

Eight different commonly applied coupling architectures are investigated. The results show that correct dimensions are of great significance for maximizing the efficiency of the energy conversion. A comparison yields the architectures with the best output performance capability which should be preferably employed in applications. A prototype development is used to demonstrate how the optimization calculations can be integrated into the design-flow.

Electromagnetic Waves and Optics: A Linear Systems Approach
by Navin KhanejaThe book explores electromagnetic (EM) waves, which are present everywhere—from radio, television, and cell phones to satellite dishes, antennas, and WiFi. The propagation of EM waves is governed by Maxwell's equations. When these waves pass through a medium, they slow down and refract, while in a metallic medium, they are reflected. Metallic boxes and pipes can store and direct EM waves, known as cavities and waveguides. Oscillating currents generate and transmit EM waves through antennas, allowing for long-distance communication after the waves propagate. Since oscillating currents emit EM waves, the author uses coaxial cables and transmission lines to reduce radiation and carry high-frequency currents efficiently. EM waves at very high frequencies in the optical range are responsible for transmitting visual information. The author also discusses lenses and optical instruments like telescopes and microscopes, which are used to magnify optical signals. Additionally, the quantum mechanical origins of a material’s permittivity, which affects the speed of light through the medium, are examined.
