Two-dimensional finite-element analysis of planar dielectric waveguides with embossed isotropic n-type semiconductor material
Abstract
Propagation characteristics and modal field distributions are
obtained for an embossed rectangular waveguide employing isotropic n
-type semiconductor material. A finite-element formulation
utilising eight-noded quadrilateral elements was used to derive the
dispersion spectrum with spurious solutions rigorously eliminated. The
canonical model analysed here employs surface plasmons in a doped
semiconducting medium as interface guided waves in the near millimetre
wave range. Such structures have potential use in the guidance and
control of millimetre waves and have applications in the design of
planar quasi-optical integrated devices
A survey chapter of the book, entitled Advances in Imaging and Electron Physics, focuses on encouraging and fostering an atmosphere of research and development based upon the properties of anisotropic semiconductors. It focuses on research and development efforts considering properties of anisotropic semiconductors under applied static magnetic fields, anisotropic chiral materials, full bianisotropic media, anisotropic ferrite under applied static magnetic fields, and undiscovered materials that result in additional or induced anisotropy. It also focuses on nonreciprocal microwave and millimeter-wave device properties resulting from the induced anisotropy. Significant attention has been given to the fundamental underlying physics of carrier transport and electromagnetic properties, as this is where the needed changes and innovations in the fields of the magnetoplasma effect, chiral phenomena, full bianisotropic media, and gyromagnetic effect in microwave and millimeter-wave devices are expected to occur.
The propagation characteristics of a plasma waveguide with a
finite thickness of cladding immersed in an external magnetic field are
presented. The effects of the collision frequency, electron cyclotron
frequency, plasma thickness of cladding on propagation constants are
investigated. Numerical investigations show that the attenuation of the
waveguide is an oscillating function of the plasma thickness of cladding
and collision frequency
The propagation characteristics of magnetoplasma waveguide coated
with a finite thickness of dielectric material are presented. Because
the boundary conditions at all interfaces can be represented by the
matrix equations, the characteristic equation can be obtained by
successively using the matrix manipulations. The dependence relations of
attenuation and dispersion of the fundamental mode with plasma
frequency, collision frequency, and electron cyclotron frequency are
shown
