Abstract: A varactor-tunable second-order bandpass frequency-selective surface (FSS) for microwave frequencies is presented in this article. The FSS is composed of three stacked metallic layers. The ...

Abstract: In this letter, a distributed periodic event-triggered (PET) consensus protocol is proposed for nonlinear multiagent systems under directed communication topology switchings. Only at the ...

The author designed a family of nonlinear static electric-springs. The nonlinear oscillations of a massively charged particle under the influence of one such spring are studied. The equation of motion ...
