| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | A thin, lightweight and flexible noise suppression sheet (NSS) made of high resistance non-magnetic metal-coated non-woven fabric has been proposed as a countermeasure against undesired electromagnetic noise resulting from printed circuit boards and cables. In this study, the proposed NSS was modeled as a continuous conductor and its shielding and conductive noise suppression mechanism were investigated through the quantitative estimation. The continuous conductor model was assumed to be a uniform conductor with the same thickness and in-plane-anisotropic sheet resistance of the NSS. The shielding effectiveness was evaluated using square waveguides with the NSS inserted. The conductive noise suppression was evaluated using a single microstrip line (MSL) with the NSS. The estimated values were approximately agreed with the experimental values. The result indicates that the shielding effectiveness and conduction noise suppression of the NSS are due to the eddy currents generated by the average conductivity of the NSS, which can be quantitatively estimated by considering the sheet resistance of NSS considering its in-plane anisotropy. | |
