Aparna Sathya Murthy in fact I search for a general solution. But in the optical regime I research now

Aparna Sathya Murthy In fact I want to know is there any cad software or theoretical method for calculation of the resonator lumped elements related to the co-planar resonators Or to the resonators in the other layers. Like something we do in the calculation of the MOSFET capacitors.
