Abstract
An electromagnetic energy harvesting device includes an emitting body at least partially embedded within a dielectric medium, and a receiving antenna disposed in proximity to the emitting body, where the receiving antenna is configured to collect thermal electromagnetic energy emitted by the emitting body. The device also includes a rectifier electrically coupled to the receiving antenna, where the rectifier is configured to convert the thermal electromagnetic energy to direct current electrical energy.
