Can a single wire in a grid polarizer produce specular reflection?

[Christofer Br]

On this wire grid polarizer the wires are less
wide than one wavelength of the incoming radiation. Is it possible to achieve a specular reflection from a single wire as shown on the image? What about reflection in the plane of length of the wire and the plane perpendicular to it (as shown)? Or does it require multiple wires so that diffuse reflections from each of them add up due to delay between reemissions (huygens principle)?

The diagram is correct, and apparently eddy currents that arise from the TE mode help cancel the transmitted TE signal. Perhaps someone with some rf experience can explain this in more detail, but the result is correct. Such polarizers can be readily constructed for microwaves, and I have used them in a laboratory class at the university many years ago. It should be noted the degree of polarization achieved will never be 100%, but in general, the diagram is correct.
