Abstract Recently electromagnetic (EM) energy harvesting using metasurfaces has gained a great attention. This presentation shows a single band and a double band polarizationindependent metasurface harvesters composed of an ensemble of new resonators with a full level of symmetry in a way that their behavior is very insensitive to the polarization of the incident wave. Loading the resonators with resistors (which model the input impedance of a rectifying circuit in a harvesting system), it is shown that the metasurface perfectly absorbs the incident EM wave (regardless of its polarization) and perfectly delivers the absorbed power to the loads.
