Need source code to simulate BOR in FDTD

please i need a source code in c++ or in to simulat BOR in FDTD to simulate an optical fiber in FDTD

thanks

what do you mean be BOR?

BOR stands for Body of Revolution. This is an integral equation technique applied to circularly symmetric object with unsymmetric excitation, for example, a plane wave incident on a missile.

Getting back to the original question ... I would look at the work of Jame Maloney and Glenn Smith. They have several paper using FDTD in cylindrical coordinates, but the paper that comes most readily to mind is "Optimization of a conical antenna for pulse radiation ..." in IEEE APS, July 1993.
