Abstract :
In this paper, a coaxial transmission line with an opening horn is simulated by using the finite-difference time-domain (FDTD) method. Since the coaxial transmission line is rotationally symmetrical, the simulation is performed in two-dimensional (2-D) cylindrical coordinate system. The deformed Yee cells near the curved PEC of the opening horn are handled by the conformal FDTD techniques. The computational domain is truncated by the PML absorbing boundary condition. Numerical results are given and some discussions are made.
