This chapter reports design and analysis methods for planar antennas based on modulated metasurfaces (MTSs). These antennas transform a surface wave (SW) into a leaky wave by means of the interaction with a MTS having a spatially modulated equivalent impedance.

Coding acoustic metasurfaces can combine simple logical bits to acquire sophisticated functions in wave control. The acoustic logical bits can achieve a phase difference of exactly π and a perfect match of the amplitudes for the transmitted waves. By programming the coding sequences, acoustic metasurfaces with various functions, including creating ...

Multiresonant Nonlocal Metasurfaces
Nano Letters, 2023Optical metasurfaces supporting localized resonances have become a versatile platform for shaping the wavefront of light, but their low quality (Q-) factor modes inevitably modify the wavefront over extended momentum and frequency space, resulting in limited spectral and angular control.

Chiral metasurface optomechanics
Conference on Lasers and Electro-Optics, 2019We report on mechanical action on light polarization, and its back-action effect, in a chiral metasurface. Our thin-film nanostructured semiconductor device may prove of relevance for fast polarization state generation and detection.

Infrared Color-Sorting Metasurface
NanoscaleThe process of sorting light based on colors (photon energy) is a prerequisite in broadband optical systems, typically achieved in the form of guiding incoming signals through a sequence of spectral filters. The assembly of filters often leads to lengthy optical trains and consequently, large system footprints.
