Acousto-optic modulation leverages the interaction between sound waves and light to control optical properties such as frequency, phase and intensity. In photonic systems, an acoustic wave propagating ...

The key parameters of the FSS technique and their impact on EMI performance. How to evaluate FSS performance using simulation, ICs, and a signal generator. Frequency spread spectrum (FSS) is a ...

A research team has achieved multilevel spin-based modulation of magnetoresistance in high-performance organic spin valve (OSV) devices. The study was published in Advanced Materials. As a new branch ...

Modulation is the process of converting data into radio waves by adding information to an electronic or optical carrier signal. A carrier signal is one with a steady waveform (a constant amplitude and ...
