A 3D printed metallized Fabry–Perot cavity antenna with improved bandwidth and low side‐lobe levels
Electronics Letters, 2021 A 3D printed metallized Fabry–Perot cavity antenna centred at 5.8 GHz is presented in this letter. A non‐uniform grid superstrate and a choke groove are employed in the Fabry–Perot cavity antenna to improve the input bandwidth and decrease the side lobes.

Analytical method to find the optimal parameters for gas detectors based on correlation spectroscopy using a Fabry-Perot interferometer [PDF]
, 2007 Several designs of infrared sensors use a Fabry-Perot Interferometer (FPI) to modulate the incident light. In this work we analyse the particular case where the FPI fringes are matched with very well defined ro-vibrational absorption lines of a target ...

Short pulse generation with 40 GHz passively-mode locked Q-dashed Fabry-Pérot laser [PDF]
, 2009 Generation of sub-picosecond pulses by a DC-biased passively mode-locked Fabry-Perot laser is demonstrated. By using a tunable band-pass filter, it is observed that the width of the generated pulses decreases in direct proportion to the optical modes ...
