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 ...

Solidly Mounted Resonators with Ultra‐High Operating Frequencies Based on 3R‐MoS2 Atomic Flakes

Advanced Functional Materials, Volume 33, Issue 29, July 18, 2023., 2023
3R‐MoS2 based solid mounted resonators with the resonant frequency up to 27 GHz and the electromechanical coupling coefficient ≈47.6% are demonstrated. Successful implantation of 2D piezoelectric 3R‐MoS2 flakes into acoustic resonators suggests that ultrathin 2D piezoelectric nanoflakes can break through the frequency limitation of conventional ...
