摘要：
In this contribution, the fundamental bounds that apply to low-scattering antennas are discussed and the use of non-linear cloaking metasurfaces is proposed to overcome them. Different power-dependent mantle cloak designs, which are able to dynamically transforming their effective geometry depending on the power level of the impinging field, are introduced. Their effectiveness is assessed in several antenna and array scenarios. This innovative approach may find applications in all those radiating systems in which a considerable difference between transmitted and received power levels is present.
