This paper presents a measurement method for the shielding effectiveness (SE) of personal computer (PC) case using three-axis electrooptic sensors and vector network analyzer (VNA). The SE is obtained by taking difference between logarithmic values ratios transmitted power to input conditions with without PC case. measurements versus incident angle polarization electromagnetic fields are perfor...

The electromagnetic interference shielding properties and the electrical of poly (methylmethacrylate) (PMMA) based composite materials prepared using different types fillers (multi-wall carbon nanotubes, black, silver coated glass microfibers) have been investigated in a broad frequency range. By combining theoretical an experimental analysis we show that, irrespective nature conductive materia...
