There is an increasing interest in energy harvesting. The rectenna, which is a combination of a rectifier and an antenna, is a device to harvest wireless energy in the air. This thesis is concentrated on the analysis, design and measurement of compact rectennas…

An optical rectenna – that is, a device that directly converts free-propagating electromagnetic waves at optical frequencies to d.c. electricity – was first proposed over 40 years ago,1 yet this concept has not been demonstrated experimentally due to fabrication…
