Calculated real part and imaginary part of complex rf conductivity vs the reduced temperature for different values of the pinning force constant, κp. The conductivity values are normalized by the normal state conductivity at the critical temperature. The large value of σ2(T = 0)/σn(Tc) is due to a large (δn/λ)2. Note also the different scales for the σ1 values.
