Abstract
A multi-layer frequency selective surface is disclosed that exhibits a frequency response having a passband and one or more stopbands.
Claims15
A multi-layer frequency-selective surface, comprising:
- a first layer comprising a first array of first metallic elements,
- a second layer comprising a second array of second metallic elements, adjacent ones of the second metallic elements being distanced by gaps from each other, and
- a third layer comprising a third array of third metallic elements,
- wherein the second layer is arranged in-between and adjacent to the first layer and the third layer.
1 more element
A computer-implemented method, comprising:
- obtaining control data indicative of a frequency,
- controlling a voltage source to bias tunable capacitors arranged in gaps between elements of an array of a frequency-selective surface.
