Abstract: The present invention provides a RF-lightwave modulator with improved efficiency by making use of a broken loop resonator having a gap therein. In the present invention a RF input signal is coupled into a broken loop resonator, thereby producing a RF output signal. An optical modulator connected across the gap receives the RF output signal and modulates a lightwave with the RF output signal to produce a RF modulated lightwave. Because the optical modulator is connected across the gap in the broken loop resonator, the voltage of the RF output signal applied to the optical modulator will be greater than the voltage of the RF input signal applied to the broken loop resonator.

Abstract: A method for designing a multiple layer frequency selective surface structure. An overall response for the structure is specified. The desired response may be modeled as a filter response. Parameters for each of the layers making up the structure that provide the overall response are determined based on the polarization modes between the layers being decoupled. To provide for decoupling, the individual layers are rotated with respect to each other. The overall response of the structure is then calculated and compared to the desired response. Adjustments are made in the parameters of each layer until the calculated response is equal or nearly equal to the desired response.
