Observation of temporal reflection and broadband frequency translation at photonic time interfaces
TL;DR: In this article , a pair of temporal interfaces are combined to demonstrate time-reflection-induced wave interference, realizing the temporal counterpart of a Fabry-Perot cavity, with opportunities for extreme photon manipulation in space and time.
Generalized Synthesis Technique for High-Order Low-Profile Dual-Band Frequency Selective Surfaces
TL;DR: In this paper, a design method for high-order dual-band bandpass frequency selective surfaces (FSSs) with a low profile is derived from classical filter theory and a multilayer double-slot resonator unit cell topology is proposed.

A Technique for Designing Multilayer Multistopband Frequency Selective Surfaces
TL;DR: In this paper, a systematic technique for designing and optimizing multilayer frequency selective surfaces (FSSs) with low overall profile is presented, where periodic scatterers in the shape of loaded dipoles (dogbones) are used on each layer to create a single-stopband response.

Analysis and Design of General Printed Circuit Board Metagratings With an Equivalent Circuit Model Approach
TL;DR: An accurate equivalent circuit model (ECM) for general multiwire multiorder printed circuit board (PCB) metagratings (MGs) is developed and it is possible to encode multiple functions into a single device by simultaneously optimizing all relevant entries of the ECM scattering matrix.

Arbitrary aperture synthesis with nonlocal leaky-wave metasurface antennas
TL;DR: This article introduces leaky-wave metasurface antennas operating at micro/millimeter-wave frequencies that are designed using the principles of quasi-bound states in the continuum, exploiting judiciously tailored spatial symmetries that enable fully customized radiation.
