In this contribution we study the fundamental interactions of a metamaterial system built of dipole elements in the THz regime. We investigate the coupling between the elements for different geometries, as well as symmetric and asymmetric structures and analyze the response of the system with changing refractive index of the surrounding medium. Finally, we use these structures to access intersubband...
A corrugated horn was design to achieve high Gaussian content horn and low reflection over an operating frequency range of 90–100 GHz was designed and verified by measurement with a vector network analyzer (VNA). The corrugated horn will be used in a W-band gyro-TWA experiment to convert TE11 mode in circular waveguide into a Gaussian-like HE11 mode. The measurement shows a lower than −30 dB reflection...
