    Abstract
  • In order to analyze antenna isolation on discrete surface, a new algorithm for ray tracing that called "minimum included angle algorithm" was proposed. First, the discrete surface was divided into triangular mesh to generate surface grid data that accord with the format required in the article. The data mentioned above was processed by using minimum included angle algorithm that was proposed in this paper. Then the length of geodesic path between any two points on discrete surface could be quickly and veraciously achieved. The length of geodesic path between any two points on cylinder, ellipse and discrete arrangement was computed, to confirm the veracity of "minimum included angle algorithm" on discrete surface.
