Title:
REFLECTION CHARACTERISTIC ANALYSIS DEVICE, REFLECTION CHARACTERISTIC ANALYSIS METHOD, AND REFLECTION CHARACTERISTIC ANALYSIS PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/012905
Kind Code:
A1
Abstract:
This reflection characteristic analysis device analyzes reflection characteristics of a dynamic reflector (Reconfigurable Intelligent Surface (RIS)). The reflection characteristic analysis device comprises a ray trace calculation unit and an electromagnetic field analysis unit. The ray trace calculation unit calculates, by using the ray trace method, an incident angle of electromagnetic waves incident on the dynamic reflector. The electromagnetic field analysis unit acquires the incident angle calculated by the ray trace calculation unit and calculates, on the basis of electromagnetic field analysis, the reflection characteristics when electromagnetic waves enter the dynamic reflector at said incident angle.
