Zusammenfassung:A computational code has been developed for analyzing 3-D radiation problems in curved geometries. To accomplish this, a suitable formulation is developed considering Maxwell equations in a general coordinate system and numerically solved by the use of a parallel curvilinear finite-difference time-domain (FDTD) method. In order to validate the computational code, the method analyzes a microstrip antenna mounted on a curved surface. The results obtained by the developed code are then compared to those generated by the conventional (orthogonal) FDTD method and by experimental measurements.
