Robust invisibility of the corrugated wires. (A) Separation between the nodal frequencies of the zeroth- and first-order scattering coefficients with respect to the scans of r2/r1 and d2/d1. (B) Calculated total scattering widths with respect to the scans of r2/r1 and d2/d1. We conclude that the nodal frequencies of the zeroth- and first-order scattering coefficients can always be tuned to coincide. Consequently, the total scattering width at this frequency would be very much compressed.
