with the rapid growth of indoor wireless communication systems, the need to accurately model radio wave propagation inside the building environments has increased. many site-specific methods have been proposed for modeling indoor radio channels. among these methods, the ray tracing algorithm and the finite-difference time domain (fdtd) method are the most popular ones. the ray tracing approach ...

Although microwaves are widely used in our daily life, their propagations left free with disordered absorption and scattering most scenes, without any sophisticated controls of paths. Microwave metamaterials have increased regulation options which cloaking is extensively studied, but exploratory aspects so far insufficient for multiple requests wireless-communication availability life space. He...

Ab&act-The dispersion relation for wave propagation in a homogeneous, electrically neutral electron gas subject to crossed static electric and magnetic fields is derived using the coupled Maxwell-Boltzmann-Vlasov equations. The cutoff condition for transverse circularly polarized electromagnetic waves is obtained from the derived dispersion relation. The variation of the cutoff frequency CO,, w...

If a quantum mechanical particle is scattered by a potential well, the wave function of the particle can propagate with negative phase time. Because of the analogy of the Schrödinger and Helmholtz equations this phenomenon is expected to be observable for electromagnetic wave propagation. Experimental data for electromagnetic wells realized by waveguides filled with different dielectrics now co...

This paper treats electromagnetic wave propagation in anisotropic, chiral and pseudochiral 3D structures. The analysis is focused on radiation and leakage behavior and includes a discussion of the effect of the media parameters on the electromagnetic characteristics of these structures.
