The purpose of this study is to obtain an optimum structure by using the optimum design method of multi-layer films under the target specifications to reflect the near-infrared light range and transmit the visible light range. We propose a method to achieve the spectral characteristics of the target specification in a wide wavelength range by combining sub-structures to high reflection of light. Generally antireflection films used in solar panels are designed for controlling only the normal incident light. In this study, a sub-structure to control the oblique incident light at a particular angle is formulated and applied to design of multilayered structure. It works not only for vertical incident light but also for oblique incident light. Furthermore the film structure is designed for controlling more wide range of oblique incident angle by laminating the resulting sub-structures. Finally multilayer films that achieved the transmission of light in the visible region and high reflection in the near infrared region for wide-angle incident light are obtained.
