A black hole energy extraction experiment has brought one of astrophysics’ most remarkable predictions into the laboratory. Researchers created a stationary electronic device that amplifies ...

Abstract: The frequency-offset-governed range-angle-dependent dynamic beam pattern of frequency diverse array (FDA) constitutes a critical mechanism for enhancing spatial-domain covertness in wireless ...

Abstract: Existing frequency-diverse array (FDA)-based jamming methods against synthetic aperture radar (SAR) still require complex modulation calculations to generate false area targets as the ...
