Summary: Resonant elements are crucial for tailoring the radiation and scattering properties of devices like antennas and functional material platforms. In this study, a simple resonator composed of a dielectric cylinder and an impedance surface is shown to support multiple scattering states. By carefully adjusting its geometry, the resonator can enhance and direct scattering, or suppress scattering to create anapole states. A prototype of the resonator using water as the dielectric and a metallic tube with slits as the impedance surface has been tested at microwave frequencies, demonstrating its flexibility in achieving different scattering responses. This resonator design has significant implications for antenna design and functional material platforms in various frequency domains, including THz and optical frequencies using high-permittivity dielectrics and graphene/nano-particle surfaces.

Summary: This work demonstrates the localization of embedded eigenstates, also known as bound states in the continuum (BICs), in a single subwavelength resonator by suitably tailoring the boundaries around it, leading to a new level of control for symmetry breaking. Experimental results show that boundary-induced BICs can be used to trace highly subwavelength perturbations in tiny water droplets, providing exciting opportunities for sensing.

Summary: We experimentally demonstrate nonlocal dielectric metasurfaces that provide both spatial and spectral control over light, focusing light exclusively over a narrowband resonance. We also realize a versatile platform for multispectral wavefront shaping, applicable in augmented reality and transparent displays.

Summary: Metasurfaces are surface equivalent of metamaterials with unconventional electromagnetic properties. Unlike metamaterials, metasurfaces are characterized by homogenized boundary conditions for electromagnetic responses. Metasurfaces can achieve extreme wavefront transformations with abrupt amplitude and phase discontinuities. This field has brought new research directions and applications to classical surface electromagnetics.

Summary: We develop a theory of bound states in the continuum (BICs) in multipolar lattices and predict their robustness to changes in lattice parameters. We also find that some multipolar lattices can host BICs forming a continuous line and carrying zero topological charge. The developed theory establishes a fundamental relation between the topological charge of BICs and the asymptotic behavior of the Q factor in its vicinity.

Summary: The study introduces quasi-bound states in the continuum (QBICs) born of chiral perturbations, encoding arbitrary elliptical polarization states and enabling geometric phase engineering. Metasurfaces with ultrasharp spectral features are designed as a result, shaping impinging wave fronts with near-unity efficiency. The findings extend Fano resonances beyond their conventional limits, opening opportunities for nanophotonics, classical and quantum optics, and acoustics.

Summary: This paper discusses four mechanisms of bound states in the continuum (BICs) in microwave and acoustic resonator systems, including symmetry-protected BICs, Friedrich-Wintgen mechanism, Fabry-Perot BICs, and accidental BICs. The method of effective non-Hermitian Hamiltonian equivalent to coupled mode theory is widely used to detect BICs.

Summary: Recent developments in microwave planar sensors have sparked renewed interest in industrial, chemical, biological, and medical applications for real-time, non-invasive material property measurements. While these sensors offer advantages such as compact size, low cost, and ease of fabrication, challenges remain in their sensitivity and selectivity. Developing high-sensitivity sensors is crucial for accurate complex permittivity measurements, and further research is needed to enhance their normalized sensitivity for broader material characterization applications.

Summary: The study reveals that quasi-bound states in the continuum of metasurfaces can provide resonant enhancement of wireless power transfer, and this physical mechanism can also be applied in resonant coupling WPT systems. It is anticipated that the results of this study can be generalized and applied in other physical systems.

Summary: This study proposes a novel approach to design ultrathin high-Q passband filters by utilizing multipolar resonances sustained by all-dielectric metasurfaces. The rigorous analytical model and numerical simulations confirm the effectiveness of the design, which can achieve high Q-factor resonances and be used for self-filtering aperture antennas with higher out-of-band selectivity.
