Active Electrically Small Antenna Based on Superconducting Quantum Array

, 2012
We introduce Superconductive Quantum Arrays (SQAs) and propose to use these structures as active Electrically Small Antennas (ESA). Several prototypes of the active ESA were fabricated using Nb process with critical current density 4.5 kA/cm2 and ...

A Unifying Model for External Noise Sources and ISI in Diffusive Molecular Communication

, 2014
This paper considers the impact of external noise sources, including interfering transmitters, on a diffusive molecular communication system, where the impact is measured as the number of noise molecules expected to be observed at a passive receiver.
