A wideband and high gain cavity-backed 4 × 4 patch antenna array is proposed in this paper. Each patch antenna element of the array is enclosed by a rectangular cavity and differentially-fed by the ...

The association of a concave macrocyclic compound to one or multiple fluorophores is an appealing strategy for the design of chemosensors. Indeed, as with biological systems, a cavity-based ...

Supramolecular cages with adjustable internal cavities are widely used as host systems for chemical sensing, catalysis, drug release, and host–guest chemistry. The accurate calculation and ...

A new wideband and enhanced gain Fabry-Pérot cavity antenna is presented in this letter. The Fabry-Pérot cavity is established between a single-layer metamaterial-based partially reflective surface ...
