Modeling and impedance matching for radio frequency driven plasma lamp considering cold and hot states. [PDF]
PLoS ONE, 2018 A new dual-state impedance matching scheme for a microwave driven plasma lamp using a solid-state power amplifier (SSPA) is presented. The impedance of the plasma lamp depends on the amount of input radio frequency (RF) energy, and therefore has very ...

Boosting electromagnetic wave absorption of Ti3AlC2 by improving effective electrical conductivity
Journal of Advanced Ceramics, 2023 Electromagnetic wave-absorbing (EMA) materials at high temperatures are limited by poor conduction loss (Lc). However, adding conductors simultaneously increases the conduction loss and interfacial polarization loss, leading to a conflict between ...

Memristive Bio-Impedance Modeling of Fruits and Vegetables
IEEE Access, 2021 Recent works show that the plants can exhibit nonlinear memristive behavior when excited with low-frequency signals. However, in the literature, only linear bio-impedance models are extensively considered to model the electrical properties of biological ...
