| Abstract: | We study transmission properties in configurations composed of two single metal gratings with different thicknesses.Choosing the perfect electric conductor excludes the influence of intrinsic material dispersion on transmission behaviors;and as such,we aim to reveal the contribution of geometric dispersion to electromagnetic transmission.Transmission suppression line,instead of a transmission suppression point, is discovered,denoting the curve of the wavelength versus the interval or the lateral displacemen... |
