中文摘要: A method of tuning transmission enhancement frequency through a subwavelength aperture is reported in this paper. A split ring resonator (SRR) loaded with lumped-element capacitances in its outer gap is placed in front of the aperture. It can be excited to resonance and then couple the localized electric field energy into the hole, enhancing the transmission. Simulation results show that as the capacitance value is varied from 0.06pf to 0.12pf, the energy transmitting through a small hole with a radius of 2.2mm is all significantly enhanced for each capacitance and transmission enhancement frequency is decreased from 6.52GHz to 5.71 GHz. Moreover, it is found that loading the capacitance in the inner gap of the SRR instead would obtain different enhancement frequency, which is shifted from 7.0GHz to 6.41GHz for the same variation of the capacitance value.
