摘要:
A power transmitter is provided that can include a microwave cavity resonant at a desired operating frequency, a hexagonal mesh top to leak evanescent fields out of the cavity, and a plurality of orthogonal monopole feeds with 90 degrees phase differences creating circularly polarized waves. The power transmitter can be configured to transmit energy to a wireless device implanted in an animal passing through the evanescent fields. Implantable devices are also described which can receive wireless energy from the power transmitter and stimulate the animals (e.g., optogenetic or electrical stimulation).
