Optical antennas are devices that convert freely propagating optical radiation into localized
energy, and vice versa. They enable the control and manipulation of optical fields at the …

The concept of optical antennas in physical optics is still evolving. Like the antennas used in
the radio frequency (RF) regime, the aspiration of optical antennas is to localize the free …

Signal-to-noise ratio (SNR) is a valuable figure of merit in determining the operating scope
of infrared detectors. Antenna-couple metal-oxide-metal diodes have been shown to detect …

The quest to harvest untapped renewable infrared energy sources has led to significant
research effort in design, fabrication and optimization of a self-biased rectenna that can …

A technique is implemented for obtaining the circular polarization in a nano-dielectric
resonator (DR) antenna. A cylindrical DR has been excited by a nanostrip feedline. The …

Our goal is to develop a rectifying antenna (rectenna) applicable to solar spectrum energy
harvesting. In particular, we aim to demonstrate viable techniques for converting portion of …

The authors have designed a new procedure for fabrication of infrared (IR) sensors. These
sensors consist of a dipole antenna coupled with a metal-oxide-metal (MOM)(Al–AlO x–Pt) …

Since the 1940s, infrared (IR) detection and imaging at wavelengths in the two atmospheric
windows of 3 to 5 and 8 to 14 μm has been extensively researched. Through several …

To improve the response performance of superconducting infrared detectors, we propose
using a photonic antenna with a micro-detector in conjunction with a nano-structure. In this …

A report is presented on the realisation and characterisation of symmetrical metal‐insulator‐
metal (MIM) diodes using the new material combination: copper‐copper oxide‐copper (Cu …
