“…The corresponding quality factors of leaky resonances depend on the degree of the introduced structural asymmetry [20]. The concept of manipulating the transition between the symmetry-protected BICs and leaky resonances was first proposed for plasmonic metasurfaces composed of metallic split-ring resonators [21], and then it was developed for all-dielectric metasurfaces [22][23][24][25][26][27][28][29][30][31]. The recent development in topological photonics has demonstrated a wide class of topologically protected states [32].…”

Metasurfaces have attracted a lot of attention in recent years due to novel ways they provide for the efficient wavefront control and engineering of the resonant transmission. We discuss an approach allowing effectively control appearance of the sharp Fano resonances in metasurfaces associated with the bound states in the continuum. We demonstrate that by breaking the symmetry transversely, in the direction perpendicular to a metasurface with a complex unit cell, we can control the number, frequency, and type of high-Q resonances originating from bound states in the continuum. As example, we demonstrate experimentally the metasurfaces with magnetic dipole and toroidal dipole responses governed by the physics of multipolar bound states.

“…Since the electromagnetic field is strongly confined inside the particles at the trapped mode resonant conditions, a metasurface can enhance several significant effects related to absorption, optical activity and optical gain. [30][31][32][33][34][35] The all-dielectric metasurfaces sustaining a trapped mode are considered as an efficient platform for the engineering optical magnetism.…”

An all-dielectric metasurface featuring resonant conditions of the trapped mode excitation is considered. It is composed of a lattice of subwavelength particles which are made of a high-refractive-index dielectric material structured in the form of disks. Each particle within the lattice behaves as an individual dielectric resonator supporting a set of electric and magnetic (Mie-type) modes. In order to access a trapped mode (which is the TE 01δ mode of the resonator), a round eccentric penetrating hole is made in the disk. In the lattice, the disks are arranged into clusters (unit super-cells) consisting of four particles. Different orientations of holes in the super-cell correspond to different symmetry groups producing different electromagnetic response of the overall metasurface when it is irradiated by the linearly polarized waves with normal incidence. We perform a systematic analysis of the electromagnetic response of the metasurface as well as conditions of the trapped mode excitation involving the group-theoretical description, representation theory and microwave circuit theory. Both polarization-sensitive and polarization-insensitive arrangements of particles and conditions for dynamic ferromagnetic and antiferromagnetic order are derived. Finally, we observe the trapped mode manifestation in the microwave experiment.

“…Traditional planar metamaterials (metasurfaces) for microwave operating range are made of periodic arrays of complex-shaped sub-wavelength metallic particles aligned on a thin dielectric substrate, or according to Babinet's principle [1], they can be formed from a metallic plate perforated with apertures of a complicated shape [2][3][4][5]. Typically, the particles are symmetrical split-ring resonators, which act as a chain of LC-circuits resulting in a resonant interaction of electromagnetic waves with a patterned layer.…”

Electromagnetic properties of a planar metallic metasurface with the design inspired by Babinet's principle are numerically studied. The metasurface is constructed from a metal plate perforated by coaxial-sector apertures. It is shown that the chosen coaxial-sector apertures make it possible to obtain a wider operating range of the metasurface than those composed of apertures of other shapes (e.g., round or rectangle). Moreover, the proposed metasurface performs an efficient polarization conversion of the linearly polarized wave to elliptically and circularly polarized ones in the reflected field.
