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： An object-detection system for, e.g., a vehicle collision avoidance system, utilizes a metamaterial-based phase shifting element array to generate a scan beam by varying the effective capacitance of each metamaterial structure forming the array in order to control the phases of their radio frequency output signals such that the combined electromagnetic wave generated by the output signals is reinforced in the desired direction and suppressed in undesired directions to produce the scan beam. The metamaterial structures are configured to resonate at the same radio wave frequency as an incident input signal (radiation), whereby each metamaterial structure emits an associated output signal by way of controlled scattering the input signal. A variable capacitance is applied on each metamaterial structure, e.g., using varicaps that are adjusted by way of phase control voltages, to produce the desired output phase patterns. The metamaterial structures are constructed using inexpensive metal film or PCB fabrication technology.
