Accurate equivalent circuit for etched resonator with effective negative permittivity
Abstract
This latter demonstrates an accurate equivalent circuit for a negative permittivity resonator using single-cell complementary split ring resonator underneath a microstrip line that introduces two attenuation poles in desired frequencies. The proposed equivalent circuit consists of lumped elements that can be accurately extracted from the measured S-parameters. Good agreement with response of equivalent circuit, electromagnetic simulation, and measurement is demonstrated. © 2006 Wiley Periodicals, Inc.
