Abstract

Characteristic impedance of MIM surface plasmon structure is analytically computed from the knowledge of propagation vector variation for different nanometric structural dimensions. Length, width, and distance between metal plates are kept in nanometer range to evaluate the propagation vector in high frequency domain, and effect of both Faraday inductance and kinetic inductance are incorporated. Notch in impedance profile is observed due to the modulation of surface plasmon propagation vector w.r.t dielectric propagation vector, and position of notch can suitably be tailored by proper choice of dimensions and material. Result provides accurate indirect measurement of the skin depth of the structure.
