COMPLEX PERMITTIVITY MEASUREMENT DEVICE, COMPLEX PERMITTIVITY MEASUREMENT METHOD, AND PROGRAM

摘要

Provided are a complex permittivity measurement device, a complex permittivity measurement method, and a program capable of highly accurately measuring the complex permittivity of a low permittivity material in a microwave region, using a measurement fixture having a simple structure, without requiring a complex measurement tool. The complex permittivity measurement device (100) comprises a fixture (110), a coaxial connector (120), a network analyzer (130), and an arithmetic processing unit (140). The fixture (110) includes: a circular first electrode (113) and a circular second electrode (111), the flat surfaces of which are disposed in parallel with and opposed to each other ; a circular opening (113b) opened at the center of the first electrode (113); and a central conductor (117) extending along the inside of an outer conductor (125) from the center of the second electrode (111) toward the outside via the circular opening (113b) of the first electrode (113).
