  A new metamaterial based, circular polarized electromagnetic energy harvester
is presented in this work. The structure, which is multilayer and utilises the
well-known to the literature geometry of the spiral split ring resonator,
operates at the Wi-Fi frequency band. Based on full electromagnetic analysis,
the proposed harvester presents high efficiency (i.e., greater than 90%),
adequate angle insensitivity (i.e., 44 deg.) and it is capable of absorbing
circular polarised plane waves.
