Electromagnetic Crystal (EMXT) based THz Components

چکیده
Various all-dielectric electromagnetic crystal (EMXT) based THz components, including filter/reflector, waveguide, antenna, and transition structure to planar circuits are proposed and simulated. Several of them have been fabricated via a THz rapid prototyping technique, and the measurements show very good consistency with the simulations. Potential integrated THz micro-systems could be constructed using these components. The layer-by-layer printing virtue of the rapid prototyping technique may enable the integration and packaging of various THz components in a systematic manner.

A W-Band Waveguide Band-Stop Filter Using Electromagnetic Crystal (EMXT) Surface
A rectangular waveguide band-stop filter using electromagnetic crystals (EMXT) surface as the top and bottom walls is presented in this letter. The EMXT surface has a band gap that can prevent electromagnetic wave from propagating along the waveguide. Dispersion properties of the waveguide filter are analyzed using an approximated lumped-element circuit model. A W-band prototype based on the pr...
متن کاملExtension of absolute-frequency measurements to the visible: frequencies of ten hyperfine components of iodine.
Direct-frequency measurements have been extended into the visible region of the electromagnetic spectrum. The visible frequencies were synthesized by generating the second harmonic of the recently measured 260-THz (20)Ne, 1.15-microm laser with a LiNbO(3) crystal. The absolute frequencies of ten hyperfine components of (127)I(2) near 520 THz are reported.
متن کاملLow frequency piezoresonance defined dynamic control of terahertz wave propagation
Phase modulators are one of the key components of many applications in electromagnetic and opto-electric wave propagations. Phase-shifters play an integral role in communications, imaging and in coherent material excitations. In order to realize the terahertz (THz) electromagnetic spectrum as a fully-functional bandwidth, the development of a family of efficient THz phase modulators is needed. ...
متن کاملOptical Constants of Two Typical Liquid Crystals 5CB and PCH5 in the THz Frequency Range.
The complex refractive indices of two benchmark nematic liquid crystal,4-4 '-n-pentyl-cyanobiphenyl (5CB) and 4-(trans-4'pentylcyclohexyl)-benzonitrile (PCH5) have been determinedin the frequency range from 0.2 to 0.8 THz. The technique of coherent THztime-domain spectroscopy (THz-TDS) was used. We show that the birefringenceof 5CB is in the range of 0.15 to 0.21, while that of PCH is from 0.01...
