Abstract: A planar immersion lens can include any number of features. A planar immersion lens can be configured to control a phase profile of an incident wave by modulating the incident wave with sub-wavelength structures of varying impedances. The planar immersion lens can also be directly excited, with electronics or other subwavelength sources coupled to the planar immersion lens, to generate a wave with the desired phase profile. The planar immersion lens can include a plurality of metallic elements and passive elements disposed over a substrate. The passive elements can be selected, based on both the intrinsic and mutual impedances of the elements, to shape the spatial phase profile of the incident wave within this phase range. The phase gradient can be introduced along the incident material/refractive material interface to focus the incident wave into the refractive material having wave components at or beyond the critical angle. Methods are also provided.

Abstract: Implantable devices and/or sensors can be wirelessly powered by controlling and propagating electromagnetic waves in a patient's tissue. Such implantable devices/sensors can be implanted at target locations in a patient, to stimulate areas such as the heart, brain, spinal cord, or muscle tissue, and/or to sense biological, physiological, chemical attributes of the blood, tissue, and other patient parameters. The propagating electromagnetic waves can be generated with sub-wavelength structures configured to manipulate evanescent fields outside of tissue to generate the propagating waves inside the tissue. Methods of use are also described.

Abstract: An apparatus can have a power supply circuit configured to receive, from an antenna, a first signal at a frequency exceeding a GHz, and including a rectifier circuit that is impedance matched to the antenna at the first frequency and that is configured to generate a supply voltage by rectifying the first signal at the first frequency. A signal generation circuit can be configured to use the supply voltage to generate a second signal at as higher frequency and to operate in two different power modes in response to a data signal. A transmitter circuit can be configured to use the supply voltage to create pulse at the higher frequency of the signal and in response to the data signal, and that includes an amplifier circuit configured to receive the data signal and provide an amplification of the data signal to the antenna.

Abstract: 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.
