Abstract

Ghost images are one of the undesired artifacts in an imaging system besides a real image. It also happens in frequency-diverse computational imaging used to reduce the complexity of traditional imaging systems using a mechanical scan or active circuits. We present that by breaking the symmetric structure of frequency-diverse wave-chaotic metasurface antennas, the ghost image artifacts in reconstructions retrieved using frequency-diverse computational imaging can be eliminated.
