Abstract (in Japanese) (See Japanese page) 
(in English) To develop a design guideline for a non-magnetic noise suppression sheet (NSS) to achieve the desired conductive noise suppression performance, the relationship between the performance and the sheet impedance Zs was investigated. The results show that the performance can be described as a function of Zs, and that the performance was maximized at approximately Zs = 100 Ω. Furthermore, using this relationship, a genetic algorithm (GA) was employed to find the conditions for the permittivity and conductivity that would realize low-pass filter characteristics with a cutoff frequency at around 20 GHz. The experiments demonstrated that an NSS satisfying these conditions achieves the design objectives of the frequency response.
