Analysis of resonant responses of split ring resonators using conformal mapping techniques [PDF]

open access: yes, 2007
We report a novel method for modeling the resonant frequency response of infra-red light, in the range of 2 to 10 microns, reflected from metallic spilt ring resonators (SRRs) fabricated on a silicon substrate.

Equivalent circuit of a dielectric in a wide frequency range (0 Hz – 500 MHz)

open access: yesФизика волновых процессов и радиотехнические системы, 2022
Based on the measured impedance of the dielectrics an equivalent high frequency (0 Hz - 500 MHz) circuit model was built. The equivalent circuit model was built taking into account the physical processes occurring in the dielectric.

The intrinsic electrical equivalent circuit of a laser diode [PDF]

open access: yes, 1981
The basic electrical equivalent circuit of a laser diode is derived. The effects of spontaneous emission and self-pulsations are included. It is found that self-pulsations are represented by a negative resistance in the model.

Electric circuit networks equivalent to chaotic quantum billiards

open access: yes, 2004
We formulate two types of electric RLC resonance network equivalent to quantum billiards. In the network of inductors grounded by capacitors squared resonant frequencies are eigenvalues of the quantum billiard.
