Designing efficient antennas with low-scattering signatures is a significant challenge due to constraints from the reciprocity principle and optical theorem. This paper explores overcoming these limitations using two approaches. The first involves non-linear cloaking devices that leverage different power levels of received and transmitted signals. The second utilizes bi-anisotropic mantle cloaks including with active elements. By applying these methods, we aim to achieve optimized scattering cancellation and effective radiation capabilities in practical scenarios.

Abstract
Designing efficient antennas with low-scattering signatures is a significant challenge due to constraints from the reciprocity principle and optical theorem. This paper explores overcoming these limitations using two approaches. The first involves non-linear cloaking devices that leverage different power levels of received and transmitted signals. The second utilizes bi-anisotropic mantle cloaks including with active elements. By applying these methods, we aim to achieve optimized scattering cancellation and effective radiation capabilities in practical scenarios.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
