This paper presents a study the electromagnetic response of unconventional superconductor and evaluated the dynamic conductivity of unconventional superconductor. For such superconductor the dynamic conductivity depends upon the frequency, temperature, scattering rate, phase shifts, find orientation relative to energy gap. The field orientation is such that points either into the dimension of vanishing energy gap ( i for the polar state and i for the ABM state) or into the dimension of maximum energy gap. Only the limiting phase shift =0 (Born approximation) and = (unitary limit) have been investigated. The real and imaginary part of arc normalised write respect to the corresponding Drude expressions.

We have shown the result of real and imaginary part of the complex conductivity n = ( = n’ + 2 ”n verses frequency for a BCS superconductor at T = 0.5 Tc for different scattering rates =0.01 T4 , = 0.1 T4 and = T4. Our theoretically evaluated results of ( n / ”n), as a function of /2 (T) indicates that the ratio is high for lower values of /2 (T) but decrease as the value of /2 (T) increase. The same decrease trend is observed for all the scattering rates. This result also demonstration the increased importance of pair breaking with decreasing . We have presented evaluated results of ratio of ( n / ”n) as a function of /2 (T) for the same scattering centers. Here also the same trend has been noticed as to for /2 (T), ( n / ”n) is large and decrease thereafter in the same fashion.
