谐振腔

Compared with analytic function, numerical data results a more precise distributing, especially for the klystrons which have narrow gaps and big size beams. In addition, The mathematical basis of AZIMUTH is a finite-difference method on squares, which results that the gap field distributing is closely correlated to cavity structure.
