University of Leicester engineers have unveiled a concept for a device designed to magnetically "cloak" sensitive components, making them invisible to detection. A magnetic cloak is a device that ...

Nanoparticles are particles that exist on a nanometre scale (i.e., below 100 nm in at least one dimension). They can possess physical properties such as uniformity, conductance or special optical ...

Abstract: A spatial multi-mode energy selective antenna integrating electromagnetic (EM) protection and anti-interference capabilities for high-intensity radiation fields (HIRF) is proposed in this ...

Abstract: We propose novel mode-dependent 3-dB power splitters based on dual-slotted multimode interference couplers. These devices are designed by using subwavelength grating structures, and our ...
