A STUDY OF THE EDGE FIELD EFFECT USING MAFIA SIMULATIONS CONFORMAL MAPPING
Brookhaven National Lab., Upton, NY (USA), Y ZHAO · 1999
It was found that the measured Q value of a tape resonator has a large difference with that calculated with MAFIA. This difference is recognized to be mainly due to the error in the simulation, which is unable to handle a sharp edge. This note addresses the 2-dimensional MAFIA simulation and conformal mapping. It shows the error could be as high as 60 %. Reasonable caution should be exercised in the use of MAFIA, and other codes as well, in calculating Q value if a sharp edge exists in the problem.
