Abstract
The current response to oscillating electric or magnetic fields acting on the carriers in the probes of a multichannel, multilead conductor is investigated. For a noninteracting system we find a frequency-depen dent admittance matrix which is expressed in terms of scattering matri ces. A self-consistent potential method is used to include Coulomb int eractions. The low-frequency departure of the admittance away from the dc conductance is discussed in terms of phase-delay times and RC time s.
