Mechanically Driven Solidly Mounted Resonator‐Based Nanoelectromechanical Systems Magnetoelectric Antennas

Advanced Engineering Materials, Volume 25, Issue 21, November 2023., 2023
Solidly mounted resonator (SMR) magnetoelectric (ME) antennas at 1.75 GHz are successfully fabricated, exhibiting an antenna gain of −18.8 dBi and a 1 dB compression point (P1dB) of 30.4 dBm. The 23.3 dB higher power handling capability than same‐size thin‐flm bulk resonator ME antenna significantly enhances robustness; manageable complementary metal ...

Dielectric response and polarization mechanism of alkali silicate glasses in gigahertz to terahertz frequency range

Journal of the American Ceramic Society, Volume 106, Issue 9, Page 5341-5350, September 2023., 2023
Abstract Oxide glasses are dielectric materials with potential applications in high‐frequency communications; hence, their dielectric properties in the gigahertz to terahertz frequency range should be investigated. In this study, the dielectric properties of silica glass and five single alkali silicate glasses were measured at 0.5–10 THz using ...
