To Study the Current Distributions of Electrically Short Dipoles in Magnetized Collisional Plasma via FDTD Simulations

Abstract

This paper presents the study of current distributions on dipole antenna immersed in warm, magnetized collisional plasma. The PF-FDTD (Plasma Fluid- Finite Difference Time Domain) model is used to model the antenna in warm, collisional and magnetized plasma. Three different types of current distributions (i.e) one-dimensional current distribution(analytical), three-dimensional current distribution(analytical), PDTD model for current distributions (numerical) are compared with each other and results are observed. These comparisons of the analytical and numerical solutions show that numerical solutions have higher resolution in analyzing the current distributions of an antenna then the analytical solutions and also the advantages and disadvantages of these different analysis methods are discussed.
