Conventional dielectric solid materials, both natural and artificial, lack electromagnetic self-
duality and thus require additional coatings to achieve impedance matching with free space …

This work aims at investigating a parity time-reversal duality (PTD) symmetric bifilar-line
waveguide structure constituted by a pair of two parallel-plate waveguides with …

The significance of antireflection has persisted over time due to its numerous optical
applications. To achieve broadband antireflection, multiple element-based designs using …

Optical properties of nonmagnetic structures that support artificial optically induced magnetic
responses have recently attracted surging interest. Here we conduct symmetry-dictated …

This communication presents an experimental validation of a backscattering-protected bifilar
edge line (BEL) constructed entirely by metallic materials. This waveguide relies on the …

Nature has long inspired scientists and engineers to develop transparent surfaces via
constructing anti‐reflective surfaces. In absence of anti‐reflection (AR) coating, silicon …

We reveal how to exploit joint spatial-electromagnetic duality symmetries to obtain invariant
scattering properties (including extinction, scattering, absorption) of self-dual scattering …

Extraordinary optical transmission (EOT) based on metallic nanohole array has great
potential for optical filtering, owing to its spectral selectivity and structure-dependent …

This paper investigates a new class of metastructures for funneling electromagnetic energy
within arbitrary narrow channels. This class is based on structures that are invariant under …

The reflection tensor of a metafilm with bianisotropic elements on a dielectric interface is
analytically derived. First, using the dipole approximation, the nanoparticles are replaced …
