When [Electron Impressions] used a powerful ultrasonic array to project a narrow beam of sound toward a target, he described it as potentially useful in getting someone’s attention from across a ...

A team from the Faculty of Physics and the Center for Quantum Optical Technologies at the University of Warsaw has developed a new type of all-optical radio receiver based on the fundamental ...

Abstract: We present the first demonstration of an acoustic quadrature amplitude modulation (QAM) circuit based on polarization switching of ferroelectric thin films. Electric field control of ...

Abstract: This letter presents an ultralow-power (ULP) 2.4-GHz envelope detector (ED)-first wake-up receiver (WuRx) for wireless body area network (WBAN) applications. A passive ED with the stepped ...

Lung cancer is a major cause of cancer related mortality due to delayed diagnosis and limited therapeutic efficiency. Early detection and effective immune modulation are important to control lung ...
