T1 - Resonant frequencies of a split-ring resonator: Analytical solutions and numerical simulations T2 - Microwave and optical technology letters N2 - A set of differential equations describing the current andvoltage distribution in a split-ring resonator is derived and solved ana-lytically. The resonant frequencies may be obtained from the solution of a characteristic equation. An approximate solution for the lowest reso-nant frequency agrees with that obtained by heuristic arguments. The analytical results are supported by numerical simulations KW - metamaterial KW - split-ring resonator KW - resonant frequencies KW - equivalent distributed circuit KW - characteristic equation Y1 - 2004 UR - https://opus4.kobv.de/opus4-oth-regensburg/frontdoor/index/index/docId/5649 VL - 44 IS - 2 SP - 133 EP - 136 PB - Wiley ER -
