Abstract

A simple equivalent circuit of recently introduced split ring resonator (SRR) is proposed in this paper. It is shown that in the vicinity of resonant frequency, the SRR can be thought of electrically small, capacitively loaded loop antenna. Due to resonant behaviour of the antenna current, intensity of the magnetic field of the incoming plane wave may be locally decreased yielding a stop-band with negative effective permeability. Theoretical analysis was verified by measurements of the transmission coefficient of experimental structures in rectangular waveguide, in 10 GHz frequency band.
