In this correspondence, we present a reconfigurable intelligent surface (RIS) that reflects an incident signal to the desired direction, depending on pulse width. This unique reconfigurability emerges by virtue of transient response embedded nonlinear circuits within RIS unit cells. The does not need any control lines connected cells or precise synchronization with base station, leading reduced...

In recent years, researchers have addressed the problem of using noncoherent approaches to estimate pulse width and repetition interval. Since measured transmitter is noncooperative, integration gain can be realized, input signal-to-noise ratio (SNR) for these estimators becomes critical. We examine multiple edge detectors that exploit moving sums calculated as part a Haar filtering received si...

Abstract— In this research, a single phase Z-source cascading Multilevel Inverter, Nine-level inverter topologies with a trinary DC sources are offered. The recommended topologies are expanded by cascading a full bridge inverter with dissimilar DC sources. This paper recommends advanced pulse with modulation technique as a switching scheme. In this PWM technology, trapezoidal modulation techniq...

Sensitive Arecibo observations provide an unprecedented ability to detect nulls for an accurate pulse-modulation quelling (PMQ) analysis. We demonstrate that a number of conal pulsars show “periodic nulling” similar to the phenomenon found earlier in pulsar B1133+16.
