A frequency selective transmittance panel has first and second conductive layers separated by dielectric spacing layer, wherein the first conductive layer comprises a plurality of unit cells, each cell comprising a conductive region at least partially surrounded by a non-conductive region, and the second conductive layer comprises a plurality of unit cells each comprising a non-conductive region at least partially surrounded by a conductive region, wherein the unit cells from the both the first and second conductive layers are of the same dimensions. The dielectric may comprise a solid dielectric, or may comprise a liquid dielectric having a variable dielectric constant. The relative dimensions of the conductive and non-conductive regions, and the value of the dielectric constant affect the peak transmission frequency through the panel. Some embodiments may have a third conductive layer spaced from the second conductive layer by a second dielectric material.
