We obtain directly the complex conductivity $\\sigma=\\sigma_1+i\\sigma_2$, the London penetration depth $\\lambda_L$, the plasma frequency $\\omega_p$, and the quasiparticle scattering rate $1/\\tau$. We find that $1/\\tau$ drops exponentially rapidly with $T$ below the critical temperature in {\\em all} the superconducting samples, implying that this behavior is a {\\em signature} of high-$T_c$ superconductivity.
