Comparing Xpatch, FISC, and ScaleME using a cone-cylinder

Many people that use computational electromagnetics to produce data are interested in two factors: speed and accuracy. To appreciate the tradeoff, it is imperative that data creation be well understood. The speed and accuracy tradeoff produces error sources. The paper compares data produced using high frequency techniques and the method of moments (MoM) accelerated by the multilevel fast multipole algorithm (MLFMA) (Chew, W.C. et al., 2001) using a cone-cylinder target. High frequency techniques break down as the target becomes smaller in terms of wavelengths. On the other hand, the MoM stretches the computing resources for increasing problem size. A missile-shaped target, a cone-cylinder called "the pencil", is used as a test object to create data for comparison using Xpatch, FISC, and ScaleME electromagnetic modeling and simulation software.
