This paper describes a novel method of characterizing complex permittivity using a
complementary frequency selective surface (CFSS). The CFSS provides a passband behavior and the change
in the passband when a material under test (MUT) is placed adjacent to the CFSS has been used for retrieving
of the complex permittivity of the MUT. The complex permittivity of the MUT are determined based on the
measured bandpass resonant frequency and insertion loss of the CFSS with the MUT. This is an amplitudeonly method where phase measurements are not required. This technique offers a convenient, fast, low-cost
and nondestructive measurement that is not restricted by the sample size or shape
