Permittivity of Rice Grain from Electromagnetic Scattering
نویسنده
چکیده
A three dimensional vector finite element method (FEM) has been used to model the permittivity of rice using the scattered far field radiation. Scattering of incident plane wave radiation is analysed to extract the permittivity of granular material. Some reduced parameters obtained from the scattered electric field show a very good correlation with the permittivity of materials (both dielectric constant and loss factor). Although the present analysis is based upon the permittivity of granular materials having dielectric constant between 1 and 7 and loss factor between 0.001 and 1.0, similar techniques could be developed for materials having different ranges of permittivity. Such analysis might be useful in solving more cumbersome problem of inverse scattering.

Abstract—This paper presents the electromagnetic interference (EMI) shielding effectiveness of rice husk and carbon nanotubes (RHCNTs) composites in the X-band region (8.2-12.4 GHz). The difference weight ratio of carbon nanotubes (CNTs) were mix with the rice husk. The rectangular waveguide technique was used to measure the complex permittivity of the RHCNTs composites materials. The complex p...

A change in the relative proportions of a mixture of rubber tire dust and rice husks will cause a change in the mixture’s electrical permittivity and its ability to absorb electromagnetic energy. An openended coaxial probe was used in conjunction with three dielectric mixture equations (the Kraszewski equation, the Landau equation and the Lichtenecker equation) to obtain the dielectric properti...
