Abstract

This paper presents the application of the finite-difference time-domain (FDTD) method in curvilinear coordinates to the analysis of conformal microstrip structures. A new near-field to far-field transformation in curvilinear coordinates is proposed. The simulated results are compared with simulations using the staircasing approximation, with published data and with measured results. © 2000 John Wiley & Sons, Inc.
