So far, one of the most accurate methods for this problem is the Vogler one whose recursive implementation is efficient to reduce the high computational complexity of the direct one. However, in the original report, Vogler only presented the final result of the recursive algorithm without a rigorous mathematical proof, thus making the method difficult to understand and implement in practice. To tackle this shortcoming, we first analyze the mathematical structure of the problem and then present a formal proof of the result. To gain intuition of the proof and the key steps, we provide a simplified study case of four knife-edges. The insight from our proposed analysis and proof can be used to obtain a comprehensive interpretation, initiate a practical implementation and develop new efficient algorithms with similar structure. date: 2020-11-18 date_type: published publisher: IEEE official_url: https://ieeexplore.ieee.org/document/9263367 id_number: 10.1109/TAP.2020.3037748 full_text_status: public publication: IEEE Transactions on Antennas and Propagation refereed: TRUE citation: Nguyen, Viet Dung and Phan, Huy and Mansour, Ali and Coatanhay, Arnaud and Marsault, Thierry (2020) On the proof of recursive Vogler algorithm for multiple knife-edge diffraction.
