Algorithm of nonequidistant segmentation of boundaries of conductors and dielectrics for computer-aided design of strip structures

Algorithm for non-uniform segmentation of the boundaries of a system of conductors and dielectrics to improve the computer-aided design of strip line structures that are widely used in radioelectronic equipment for various purposes is proposed. The algorithm is based on the adaptive iterative choice of optimal segmentation and the previous iteration information about the surface charge density at the boundaries of the analyzed system. Features of algorithm implementation are described. Several variants of its implementation are considered. On the example of calculating a capacitive matrix of three configurations, the operation of proposed algorithm and of algorithms using uniform segmentation is compared. The effectiveness of the proposed algorithm from the point of view of minimizing the computing costs is shown.
