Effect of Material on Electromagnetic Shielding
Designed and ran a controlled experiment measuring how enclosure materials shield FSAE electronics from motor EMI, finding aluminum tube shielding cut interference by 92%.
Highlights
- Communication-intensive class covering experimental design, statistics, and data acquisition
- Simulated motor EMI with a coiled-wire antenna driven by an electric drill
- Compared aluminum tape, foil, and tube shielding against an unshielded control
- Aluminum foil and tube produced statistically significant shielding improvements (p < 0.001); tube reduced interference by 91.9%
