We present a hybrid approach for graphene modeling in the finite element method numerical simulations of graphene based plasmonic devices with COMSOL. The surface conductivity approach for modeling graphene or other two-dimensional materials needs le

Abstract Square loop and square slot are the simplest and commonly used elements of frequency selective surfaces (FSSs) providing bandstop and bandpass responses, respectively. Despite it is already known that employment of a double square slot struc

Subwavelength plasmonic wires provide a very simple, ultracompact, and efficient platform for active plasmonics. We theoretically investigate magnetically switched transparency in subwavelength semiconductor wires. The main difficulty limiting the pe

In most studies on all-optical diodes, spatial asymmetry has been by necessity applied to break Lorentz reciprocity. Here we suggest a paradigm for optically induced nonreciprocity in semiconductor wires which are spatially asymmetry-free and provide

The waveguide-coupled plasmonic nanocavity is known to be a deep subwavelength platform that combines on-chip compatibility with a strong light-matter interaction at the resonance of local field enhancement; however, the resonant local field enhancem

Magnetic field detuning of the surface plasmon-polariton (SPP) resonance is one of the most popular schemes for magnetoplasmonic devices and subwavelength optical isolators. The main difficulty limiting their performance is the need to use a strong m
