complex supcond(double freq, double T, double Vgap, double Tc);

// ******************************************************************
//     calculate complex conductivity of a superconductor in the local limit
//
//     Input variables:
//        freq - frequency
//        T - temperature 
//        Vgap - energy gap voltage of superconductor at T=0
//        Tc - critical temperature
//     These variables use standard units as defined in units.h
//
//     Return value: Superconductor complex conductivity 
//     normalized to normal-state conductivity
//     This is dimensionless so units don't matter
//
// ******************************************************************
//     The sign of the imaginary part is chosen to be consistent
//     with the standard EE convention of exp(+j omega t) for
//     harmonic time dependence
