A simple and efficient method for determining the stability of optical vortices via Fourier transform using a conventional spherical lens is presented. The theoretical and experimental results demonstrate a practical approach to directly and unambiguously measure the magnitude and sign of the topological charge of a beam without altering an ...

Cloaking and Antennas: From Theoretical Paradigms to Next‐Generation Intelligent Systems
The inception of electromagnetic cloaking sparked an immediate question: Can antennas be made invisible? Two decades later, this review charts the intertwined progress of major cloaking strategies (from transformation optics to scattering cancellation), metasurface technology, and their application to antennas, revealing how AI‐enabled devices are ...

Fast and Reversible Red Emission Modulation in Photoswitchable Molecules Toward Optical Data Storage
A series of intense red‐emitting BTCPO4 photoswitches is synthesized, and their photophysical properties, such as fluorescence quantum yield, fatigue resistance, and reversible cyclization, are reported. The issue of slow reverse cyclization, which hinders fluorescence modulation (ON‐OFF) of these molecules, is overcome by utilizing energy transfer to ...

Under the influence of an electron beam, the photoluminescence (PL) and quantum sensing stability of nitrogen‐vacancy (NV) centers in fluorescent nanodiamonds (FNDs) change. This work elucidates structural and functional changes induced by the electron beam in FNDs and identifies imaging conditions to preserve NV properties and offers a pathway for top‐
