چکیده
Abstract In this paper, the characteristics of transmission coefficient (S $$_{21}$$ 21 ) measured in free-space at terahertz frequencies are analyzed. The analysis results used to estimate permittivity material under test, and estimated is adopted as an initial-value for iterative algorithm extract complex from S . extraction technique based on estimation efficient, while without inefficient. Various known materials literature validate band.

Ground penetrating radar (GPR) is based on high-frequency electromagnetic wave propagation and its detecting targets are below the ground surface (Daniels, 2004; Jol, 2009). Velocity and attenuation are two important factors describing the electromagnetic wave in the media composed of rocks or soils. Velocity is inverse proportional to the root of the permittivity while other parameters are fix...

A dielectric mixing model has been developed to calculate the complex permittivity of wet soils at 5.65 GHz (C-band) and 9.5 GHz (X-band) microwave frequencies. The model considers the complex permittivity of dry soil as initial parameter. The complex permittivity of wet soil has been estimated in terms of the complex permittivity of dry soil, the complex permittivity of water at a given microw...
