Electromagnetics of Time Varying Complex Media: Frequency and Polarization Transformer

0.0

Recent advances in the fields of materials science and electromagnetics indicate that materials can be synthesized with any desired electromagnetic properties. Electromagnetics of Complex Media provides the appropriate understanding of optimum properties for a given application, addressing the needs of researchers who study electromagnetics as a base for those disciplines using complex materials. Examples include electrooptics, plasma science and engineering, microwave engineering, and solid state devices.The book emphasizes these aspects: Dispersive medium Tunneling of power through a plasma slab by evanescent waves Characteristic waves in an anisotropic medium Transient medium and frequency shifting Green's function for unlike anisotropic media Perturbation technique for unlike anisotropic media Adiabatic analysis for modified source wave All of the above topics use one-dimensional models. Brief discussions also include chiral media, surface waves, and periodic media. The text focuses on bringing out the major effects due to each kind of complexity in the medium properties. A plasma column in the presence of a static magnetic field is at once dispersive, anisotropic, and inhomogeneous - thus the author uses plasma as the basic medium to illustrate some aspects of the transformation of an electromagnetic wave by a complex medium. Early chapters use a mathematical model that usually has one kind of complexity. The medium is often assumed to be unbounded in space or has a simple plane boundary. The field variables and the parameters are often assumed to vary in one spatial coordinate. This eliminates the use of heavy mathematics and permits the focus to be on the effect. Electromagnetics of Complex Media aims to stimulate experimental and additional theoretical and numerical work on the effects that can be obtained by the temporal and spatial modification of the magnetoplasma parameters. The book also provides the new researcher with a quick primer into the theory of using magnetoplasmas for the coherent generation of tunable radiation.
