Varying the voltage of a carrier or a direct current in order to transmit analog or digital data. Amplitude modulation (AM) is the oldest method of transmitting human voice electronically. In an ...

The paper presents the results of a comprehensive study on the optimization of independent amplitude and phase wavefront manipulation which is implemented using a binary digital micromirror device.

Two-dimensional (2D) space-encoded metamaterials enable the progressive development of a multitude of functionalities for controlling electromagnetic (EM) waves. Recently, time-modulated phase-coded ...
