A Concise and Time-efficient Method for Characterizing the Permittivity of Unknown Materials [PDF]
Journal of Electromagnetic Engineering and Science, 2023 We propose a simplified and time-efficient methodology to characterize the permittivity of unknown materials. Based on the transmission line method, this method enables permittivity extraction using a small number of dielectric materials under test (MUT).
