摘要： A metamaterial-based phase shifting element utilizes a variable capacitor (varicap) to control the effective capacitance of a metamaterial structure in order to control the phase of a radio frequency output signal generated by the metamaterial structure. The metamaterial structure is configured to resonate at the same radio wave frequency as an incident input signal (radiation), whereby the metamaterial structure emits the output signal by way of controlled scattering the input signal. A variable capacitance applied on metamaterial structure by the varicap is adjustable by way of a control voltage, whereby the output phase is adjusted by way of adjusting the control voltage. The metamaterial structure is constructed using inexpensive metal film or PCB fabrication technology including an upper metal “island” structure, a lower metal backplane layer, and a dielectric layer sandwiched therebetween. The varicap is connected between the island structure and a base metal structure that surrounds the island structure.

摘要： A radio frequency (RF) energy harvesting device including a scalable metamaterial resonator antenna and a rectifying circuit formed on a flexible plastic substrate. The metamaterial resonator antenna includes a metal (e.g., silver) structure that is conformally fixedly disposed (i.e., either printed or deposited/etched) on the flexible substrate and configured to resonate at RF frequencies using primary and secondary antenna segments connected by linking segments such that captured RF signals are generated at two antenna end points that are 180° out-of-phase with each other. The rectifying circuit including additional metal structures that are also printed or otherwise formed on the flexible substrate, and one or more circuit elements that are configured to pass positive voltage pulses from the captured RF signals to an output node. Various metamaterial resonator antenna configurations are disclosed.

摘要： A solar power system includes a sunlight concentrating system (e.g., a heliostat), a thermophotovoltaic (TPV) converter and a thermal power system. The TPV converter includes a metamaterial emitter formed on a box-like enclosure, and an associated photovoltaic (PV) cell. The sunlight concentrating system directs the concentrated sunlight through an inlet opening of the box-like enclosure to heat the metamaterial emitter above 1000° K. Bull's eye structures formed on outward-facing surfaces of the box-like enclosure utilize concentric circular ridges spaced at a fixed grating period that, when heated, generate a radiant energy beam having a peak emission wavelength roughly equal to the grating period. The PV cell converts the radiant energy to produce primary electrical energy. Unconverted solar “waste” heat energy exits the box-like enclosure and is converted by the thermal power system (e.g., using a steam generator) to produce secondary electrical energy.
