Figure 3: The fishnet metamaterial under coherent excitation.
From: Coherent selection of invisible high-order electromagnetic excitations
(a) Absorption spectrum of the sample under traveling-wave excitation, together with the two coherent absorption spectra with the sample at the E-antinode and the B-antinode of a standing wave. (b–d) The magnetic field intensity in the middle plane of the metamaterial under the three different excitation conditions. The excitation wavelength is 820 nm for all three cases.
