One-click electromagnetism at the nanoscale
The wires couple: with light polarized across the gap, the field in a narrow gap between two metal wires becomes much stronger than near a single wire, and the resonance red-shifts as the gap closes.
Yes: the scattered fields of both cylinders are coupled with the exact addition theorems, converged in the number of orders.
Yes: choose each wire's material, diameter and shells, and their arrangement relative to the incoming light.
