    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.

    Abstract: A device for varying the capacitance of an electronic circuit is disclosed. The device comprises a flexible membrane located above the electronic circuit, a metal layer connected to the flexible membrane, and bias circuitry located above the membrane. Variation of the capacitance of the electronic circuit is obtained by pulling the membrane upwards by means of the bias circuitry. The disclosed device provides a sizeable capacitance variation and high Q factor, resulting in overall low filter insertion loss. A nearly constant group delay over a wide operating bandwidth is also obtained.
