Wideband Gyro-Amplifiers [PDF]
IEEE Transactions on Plasma Science, 2012 Gyro-amplifiers using helically corrugated waveguides have shown exceptional gain, power, bandwidth, and efficiency performance at cm and mm wavelengths. The performance of a long pulse (and therefore high vacuum) system is strongly influenced by factors other than the intrinsic bandwidth of the interaction. We shall discuss these and other challenges,

EURASIP Journal on Advances in Signal Processing, 2005 Summary: The application of ultra-wideband (UWB) technology to low-cost short-range communications presents unique challenges to the communications engineer. The impact of the US FCC's regulations and the characteristics of the low-power UWB propagation channels are explored, and their effects on UWB hardware design are illustrated.

CPW Fed UWB Antenna by EBGs With Wide Rectangular Notched-Band
IEEE Access, 2016 Ultra-wideband (UWB) antennas with wide rectangular notched-band are proposed in this paper. The rectangular notched-band design is realized by placing dual mushroom-type electromagnetic-bandgap (EBG) structures on the CPW feeding line.

An Electrically Tunable Terahertz Filter Based on Liquid-Crystal-Filled Slits with Wall Corrugations
Photonics, 2022 We propose a type of hollow planar waveguide with corrugated walls, which can realize electrically tunable terahertz (THz) filtering by filling the slit with liquid crystals. When the THz signals propagate in a planar waveguide with periodic corrugations,

Nanoscale Research Letters, 2018 Terahertz electromagnetic (EM) wave components usually have a single function, such as they can only convert the polarization state of an incident wave or absorb the incident energy, which would be a limitation for their applications.
