Metasurfaces as optically thin composite layers can be modeled as electric and magnetic
surface current sheets flowing in the layer volume in the metasurface plane. In the most …

Subwavelength dielectric resonators assembled into metasurfaces have become a versatile
tool for miniaturizing optical components approaching the nanoscale,–. An important class of …

Willis coupling in acoustic materials defines the cross-coupling between strain and velocity,
analogous to bianisotropic phenomena in electromagnetics. While these phenomena have …

Angstrom precision localization of a single nanoantenna is a crucial step towards advanced
nanometrology, medicine, and biophysics. Here, we show that single nanoantenna …

The bianisotropy of meta-atoms is usually associated with their nonlocal response and
mutual coupling between electric and magnetic dipole moments induced by an incident …

Optical nonreciprocity is manifested as a difference in the transmission of light for the
opposite directions of excitation. Nonreciprocal optics is traditionally realized with relatively …

Nowadays, dielectric metasurfaces are a promising platform in many different research fields
such as sensing, lasing, all-optical modulation and nonlinear optics. Among all the different …

Microwave-induced thermoacoustic imaging (MTAI) using low-energy and long-wavelength
microwave photons has great potential in detecting deep-seated diseases due to its unique …

We propose a high-resolution microscopy technique for enantiospecific detection of chiral
samples down to sub-100-nm size based on force measurement. We delve into the …

It has been observed that achiral nanoparticles, such as flat helices, may be subjected to an
optical torque even when illuminated by normally incident linearly polarized light. However …
