In this paper, we provide a comprehensive review of unidirectional reflectionless light
propagation in photonic devices at exceptional points (EPs). EPs, which are branch point …

Metamaterial perfect absorbers (MPAs) are artificial materials composed of an array of
subwavelength structures that manipulate electromagnetic waves to achieve extraordinary …

The effect of electromagnetic (EM) resonance in the graphene resonator and multiple
reflections taking place in the dielectric spacer can provide the multiband infrared …

A simple design of an ultrathin six-band polarization-insensitive terahertz perfect
metamaterial absorber (PMMA), composed of a metal cross-cave patch resonator (CCPR) …

We design a non-parity-time-symmetric plasmonic waveguide-cavity system, consisting of
two metal-dielectric-metal stub resonators side coupled to a metal-dielectric-metal …

We present the design and numerical simulations of a broadband plasmonic light absorber
(PLA) based on a tungsten meander-ring-resonator (MRR) structure in visible region. The …

We demonstrate an ultra-sensitive photodetector based on a graphene/monolayer MoS2
vertical heterostructure working at room temperature. Highly confined plasmon waves are …

Atmospheric windows play an important role in the field of infrared detection and radiative
cooling. In this paper, the development of VO_2-based metamaterial emitter brings …

Polarization-and incident-angle-independent narrow-band terahertz (THz) absorbers were
developed to enable THz imaging, radar, and spectroscopy applications. The design …

A terahertz tunable graphene ribbon-array coupled with a sheet absorber, which has the
near-unity absorption and wide absorption bandwidth, is proposed and studied in this letter …
