REPORT ON APPLIED RESEARCH PROGRAM IN ELECTROMAGNETIC ENERGY RAY PATHS. PART II. ANALYTICAL DESCRIPTION.
Abstract
The report is subdivided into 3 major sections: (1) general description of the ray tracking method, (2) work performed in these problem areas, (3) a summary of all work produced. Efforts were made on ionogram reduction and data smoothing for use in a Hamiltonian Ray Tracing Program which uses Haselgrove's form of Hamilton's electromagnetic wave equations. Emphasis in this work has been placed on analog to digital as well as possible digital to hybrid compatibility. Power losses due to refraction and inverse square law spreading have been computed using a single ray approach. The method is fully described. Ray Tracking has been done with and without magnetic field. Comparison of these results led to the discovery that the magnetic field has a pronounced effect on the ray path even at frequencies much greater than 15 MHz when the path traveled is north-south, or along magnetic field lines. Tabulated results and the underlying factors in the argument are presented. Part II supercedes Part I of this series of reports. (Author)
