Abstract :
Both complex and real multipole resonance frequencies in radar cross section (RCS) of a dielectric sphere are studied in some detail. Charts of real resonance frequencies and peak values are presented, which are then used to determine the complex permittivity of the material from the resonance measurement. The results show the possibility of highly accurate measurement at microwave frequencies. This method is unique in several respects and has many advantages.
