It can give rise to ultrahigh Q-factor beyond 104 in the THz regime. Experimentally, the measured Q-factor of dominant magnetic dipole resonance can achieve no less than a level of ~261 by Lorentzian fitting to the experimental data. In addition, a high Q-factor of the fundamental-order magnetic

Note that the forward scatter equals the backscatters and at q = 90o scattering WebMultiple scattering of polarized electromagnetic waves in diffusive media is investigated by means of radiative transfer theory. This approach amounts to summing the ladder diagrams for the diffuse reflected or transmitted intensity, or the cyclical ones for the cone of enhanced backscattering. The method becomes exact in several situations of interest, …
