▲ [20a-PA3-3] Parallel Calculation for Electromagnetic Field with Local Fourier Coupled Mode Theory
Keywords:Computational electromagnetic methods, Parallel processing, Computational optics
Recently, as the display rapidly develops, a lot of research and development related to display technologies are being carried out. In particular, organic light emitting diode (OLED) display devices have complicated optical structures on the nanoscale and different luminescent properties depending on the polarization of light. To analyze OLED displays with complicated structures, we used the Fourier Mode Method (FMM) based on rigorous coupled-wave analysis (RCWA) to calculate the EM field. In this paper, we propose a method for parallel process of FMM that can perform calculations on general level calculation systems such as a personal computer (PC). Our approach is the derivation of the parallel FMM based on the coupled mode theory (CMT) and free-space extension technique. This algorithm allows efficient calculation of the EM field of a large area display through parallel FMM. This method is expected to contribute to the problems of the OLED display field that have not been solved yet.
