TLDR
In this paper, the transmission properties of a lattice of split ring resonators for different electromagnetic (EM) field polarizations and propagation directions were investigated. And the authors found that the incident electric field E couples to the magnetic resonance of the SRR when the EM waves propagate perpendicular to SRR plane and the incident E is parallel to the gap-bearing sides of SRR. This is manifested by a dip in the transmission spectrum.
Abstract
We study both theoretically and experimentally the transmission properties of a lattice of split ring resonators (SRRs) for different electromagnetic (EM) field polarizations and propagation directions. We find unexpectedly that the incident electric field E couples to the magnetic resonance of the SRR when the EM waves propagate perpendicular to the SRR plane and the incident E is parallel to the gap-bearing sides of the SRR. This is manifested by a dip in the transmission spectrum. A simple analytic model is introduced to explain this interesting behavior.
