摘要：
The four boundary cell is an important arrangement for the measurement of complex permittivity of bulk solids and liquids. Transcendental equations for reflection and transmission are derived and previous errors in the literature are noted. This measurement method is extended to granular samples where a compression technique is introduced to minimize the dispersion in S-parameter measurements associated with interface problems.
