If you have another question then it's best to open a new question so that others can discover it as well. However, the short answer is that the propagation constant depends on the metal, the aperture medium, and the geometry of the aperture. | |

I was just wondering how, for the case of an EM wave tunnelling through an aperture below cut-off width, the propagation constant is different from an EM wave tunnelling through an optically thin metal sheet? In the case of an aperture being present, does this result in an effective propagation constant being used which is dependent on the metal and the medium filling the aperture? | |
