WebAug 5, 2024 · A tutorial overview is presented on the principles of operation, physical modeling, and design procedures for the class of planar radiators known as Fabry-Perot cavity antennas (FPCAs), with an emphasis on their characterization as 2D leaky-wave antennas (LWAs). After recalling their principal radiative features, alternative … In optics, a Fabry–Pérot interferometer (FPI) or etalon is an optical cavity made from two parallel reflecting surfaces (i.e.: thin mirrors). Optical waves can pass through the optical cavity only when they are in resonance with it. It is named after Charles Fabry and Alfred Perot, who developed the instrument in 1899. Etalon is from the French étalon, meaning "measuring gauge" or "standard".

WebNov 29, 2024 · A novel dual-polarized Fabry-Perot (FP) cavity antenna with low sidelobes is proposed. Low sidelobes are obtained by using a tapered partially reflective surface (PRS) in the form of circular lattice instead of the conventional rectangular lattice. As the PRS can be regarded as a 2D leaky wave surface on which cylindrical waves propagate ... WebMay 24, 2024 · EOT in the IR wavelength region is very important for realizing various optical filter applications. Therefore, in this study, hBN embedded in 1D nanoslits with a high aspect ratio (narrow slit width and high slit height) is proposed. Such 1D nanoslits produce EOT due to the hybridization of the Fabry–Pérot resonances of SPRs . By …
WebA classic Fabry–Perot interferometer is formed by two closely spaced, partially reflecting mirrors which form a resonant optical cavity with maximum optical transmission at wavelengths that are multiples of the mirror spacing, at small incident light angles (see Figure 2-10 ).
