Modeling energy availability in RF Energy Harvesting Networks
2016 International Symposium on Wireless Communication Systems (ISWCS), 2016In a Radio Frequency (RF) Energy Harvesting Network (RF-EHN) the nodes have the capability of converting received electromagnetic RF signals in energy. Traditionally, the RF signals are provided by high power transmitters operating in the neighborhood of the harvesters.

Waveform-aware ambient RF energy harvesting
2014 IEEE International Conference on RFID (IEEE RFID), 2014In this paper we suggest a new class of RF energy harvesters, which we call “waveform aware harvesters”. In contrast to traditional rectenna designs, which are usually designed for high efficiency with continuous wave (CW) signals, waveform aware harvesters are RF to DC converters which are optimized for their performance with non-CW signals.
