A Lossy Coated Thin Wire Model Based on the Unconditionally Stable Associated Hermite FDTD Method
View through CrossRef
This paper presents a lossy coated thin wire model based on the unconditionally stable (US) associated Hermite finite-difference time-domain (AH FDTD) method. The normal electric field discontinuity between lossy coated and surrounding media is corrected as the time-domain boundary condition. The coefficient matrix equation of lossy coated thin wires in AH domain is deduced by the static field model of infinite thin wires and the Faraday’s law contour-path formulation, finally the thin wires with lossy coated is modeled. Three examples of dipole antenna, five-element Yagi antenna and square antenna are used to verify the accuracy and high efficiency of the lossy coated thin wire model. The results show that the model can maintain the relative error of less than -26 dB and reduce computation time compared with the traditional FDTD method.
