Abstract
We have measured the surface impedance Zs=Rs+iXs in the normal and superconducting states of κ(BEDT-TTF)2Cu(NCS)2, and have evaluated the conductivity σ1. The temperature-independent Xs for T≪Tc and the weak maximum observed for σ1 below Tc rule out unusual pairing. Our results are in good overall agreement with calculations based on a BCS ground state.
