We present a method for determining the four-port S-matrix of the external coupling network (ECN) for symmetric, two-element biomimetic antenna arrays (BMAAs) by employing singular value decomposition (SVD). The presented approach greatly facilitates

Metasurfaces composed of cylindrical dielectric resonators, responding either in optical or microwave ranges, are investigated with the goal of clarifying common features of their electromagnetic responses and their transformations at variations of a

Parameters of unit cells in metasurfaces (MSs) are usually determined by applying the infinitely periodic conditions in numerical analysis. However, real-world samples of MSs are implemented with finite number of resonators. We conduct studies to rev

A strongly modulated photonic crystal with rectangular lattice was designed to realize the collimation effect for diverging waves entering the crystal at frequencies, providing near-zero refractive indices at unidirectional transmission.

We investigate lattice resonances (LRs) in metasurfaces (MSs), composed of silicon nano-cylinders. It is revealed that LRs can be detected through concentration of fields at specific locations in the gaps between nano-cylinders. Formation of LRs appe

We investigate the effects of fragmenting metasurfaces (MSs), composed of dielectric disks, on their electromagnetic responses and show that the presence of four abrupt boundaries between finite size structures and free space leads to the formation o

An analog of electromagnetically induced transparency was revealed in metasurfaces (MSs), composed from identical dielectric resonators of simple cylindrical shapes. It was detected in numerical experiments at optical and microwave frequencies and co
