Broadband Plasmonic Bandstop Filters With a Single Rectangular Ring Resonator

A broadband plasmonic bandstop filter with a single directly connected rectangular ring resonator is proposed. Inside this resonator, which is constructed using two nonidentical branches, both ring resonance and Mach-Zehnder interference occurred. A broad stopband can be realized by appropriately ad...
