Abstract Line waves (LWs) refer to confined edge modes that propagate along the interface of dual electromagnetic metasurfaces while maintaining mirror reflection symmetries. Previous research has both theoretically and experimentally investigated th

In this work, we propose a pseudospin-polarized closed waveguide whose walls are formed by dual electromagnetic boundary conditions. The structure has a very wide bandwidth so that it covers an extremely wide electromagnetic spectrum. The proposed wa

Line waves are distinct modes that arise along a line that connects two-dimensional impedance surfaces with a dual electromagnetic response. In general, line waves can be implemented using complementary impedances or impedances with a gain-loss effec

We propose an ultra-broadband, ultra-compact and a dynamically tunable power splitter on a silicon on Insulator (SOI) platform with a 220 nm thick silicon light-guiding layer, using two multimode interference (MMI) couplers connected with graphene-ba

An ultra-broadband absorber of light is proposed by using periodic array of ultra-thin metallic ribbons on top of a lossless quarter-wavelength dielectric spacer placed on a metallic reflector. We propose a fully analytical circuit model for the stru

A hybrid plasmonic-dielectric metasurface is proposed in order to manipulate beam propagation in desired manners. The metasurface is composed of patterned hybrid graphene-silicon nano-disks deposited on a low-index substrate, namely silica. It is sho

Inspired by the reflectarray concept, we propose a polarization beam splitter (PBS) using orthogonally oriented slotted graphene patches configured in a two-layer metasurface, which bidirectionally deflects the incident wave depending on its polariza
