Complex Permittivity Measurement Based on Transmitted Power

This paper presents a novel complex permittivity measurement using transmitted-power function enforced at multiple frequencies. The method can easily retrieve the dielectric constants of low-loss and lossy materials utilizing the transmitted power without the need for phase information. Simulations results show a high accuracy level of the proposed permittivity reconstruction technique, making the technique an attractive candidate for fast and inexpensive complex permittivity determination without the need for a vector network analyzer.
