Abstract

A new set of equations have been developed for cavity perturbation technique for the measurement of complex permittivity at microwave frequencies. These newly derived formulas are more general than the standard forms in that the material sample under investigation could have a sample length shorter than the height of the cavity resonator. These new equations have been proved to be adequate in yielding accurate results by measuring different samples with different lengths. The cavity under consideration is a rectangular cavity and operated in TE _10L mode
