Numerical and Experimental Impedance Analyses of Dipole Antenna in the Vicinity of Deionized Water at Different Temperatures

抄録

This paper includes different approaches for analysis of a thin-wire antenna in the presence of de-ionized water box at different temperatures as a high-permittivity three-dimensional dielectric body. In continuation with the previous work of authors, first, the coupled tensorvolume/line integral equations is solved by using Galerkin-based moment method (MoM) consisting of a combination of entire-domain and subdomain basis functions including three-dimensional polynomials with different degrees. Then, the accuracy of such MoM, specifically for a highpermittivity dielectric scatterer, is substantiated by comparing its numerical results with that of FDTD method and some experimental data.
