Abstract |
This paper presents two methods of analysis of the complex moving waveguide. One approach is a numerical technique based on Davidenko's method, the other is a perturbation method. It is clear that if one wants to obtain more accurate results over a wide range it is necessary to develop numerical techniques capable for solving lossy waveguides that has a complex propagation constant or a complex dielectric constant. Newton's method is one of these methods which requires several iterations in the complex plane, but this method fails in most cases in producing satisfactory results. Davidenko technique offers an alternative which is efficient and reliable and which relaxes the extent of the restriction placed on initial guess to be sufficiently close to the solution. The main idea of Davidenko's algorithm is to reduce Newton's method for the numerical solution of n-coupled nonlinear algebraic equations into n-coupled … |
