Dielectric resonator are high permittivity ceramic structures which couple easily into planar and waveguide circuits. One of their more practical uses is in realizing high Q tuned circuits on planar microwave circuits. For such applications the important resonator parameters are, the resonant frequency, the Q of the mode and the coupling coefficients, among others. Most of the work in the past on...
Three approaches will be presented for low-cost sub-millimeter/THz integrated circuits and systems. Multi-layer planar line monolithic integration, dielectric waveguide hybrid technology, and SOI-based photonic-crystal technique will be described and recent progresses and typical developed integrated devices will be discussed.
A cylindrical metallic photonic crystal waveguide -design and analysis is reported. Air-core microstructured fiber has been demonstrated as a low loss dielectric waveguide for THz guiding is used to design this waveguide. It can be used as a slow wave structure (SWS), which is considered as a key element in backward wave oscillator (BWO) and other types of electron beam sub-millimeter wave sources...
