Reconfigurable intelligent surface (RIS) is a revolutionary technology to enhance both the spectral efficiency and energy of wireless communication systems. However, most existing contributions mainly focused on study passive RIS, which suffers from “double fading” effect. On other hand, active equipped with amplifiers, can effectively address this issue. In letter, we propose an RIS-aided simu...

Simultaneous Wireless Information and Power Transfer (SWIPT) is an emerging field to transmit information power in IoT network through the same RF signal. Time switching (TS) protocol more favorable free space communication than Splitting (PS) when transmitted signal already weak. This because, loses its due attenuation space, using PS design receiver circuit (complex), received weak further sp...
