Abstract
A method, system, apparatus, and computer readable medium has been provided with the ability to obtain a complex permittivity ∈ or a complex permeability μ of a sample in a cavity. One or more complex-valued resonance frequencies (fm) of the cavity, wherein each fm is a measurement, are obtained. Maxwell's equations are solved exactly for ∈, and/or μ, using the fm as known quantities, thereby obtaining the ∈ and/or μ of the sample.
