The Fabry-Pérot cavity antenna represents a significant advance in antenna design, harnessing the principle of multiple reflections between a ground plane and a partially reflective surface to achieve ...

An optical structure containing a pair of mirrors at opposite ends of a cavity. Light reflects back and forth between the mirrors, and one or both transmit a fraction of the resonant frequency. The ...

Trace gas sensors are used in different fields. Light-induced thermoelastic spectroscopy (LITES) has extremely high sensitivity and offers non-contact measurement, attracting extensive research ...
