数値解析・応用解析セミナー 4月24日(火) 15:30 -- 17:00 Gottfried Bruckner (Weierstrass Institute, Germany) ``On the inverse problem of diffractive optics: The reconstruction of 2D gratings'' <研究発表要旨> This is a survey on some approaches from literature and on my own approach (together with J. Elschner: Weierstrass Institute) using an idea of Kirsch and Kress concerning their 3D obstacle inverse scattering. It is a Levenberg-Marquardt algorithm being very near to Tikhonov regularization. First calculations concern the easiest case of a constant grating only. セミナー室: 京都大学 工学部2号館4階 414号室 (応用解析学講座セミナー室)
