Electromagnetic Compatibility Measurements of Polymers in the Automotive Industry: Shielding Effectiveness According to ASTM D 4935 — Leopold Handke, Nicola Peranio, and •Verena Cerna — Technische Hochschule Ulm, Ulm, Deutschland

Electromagnetic compatibility (EMC) is a key concern in the automotive industry due to the growing complexity of vehicle electronic systems and the need to prevent electromagnetic interference that could affect their performance and safety. Polymers used in automotive components must meet specific EMC requirements to ensure proper functioning of vehicle electronics. This study investigates the shielding effectiveness (SE) of various polymer materials using standardized measurements according to ASTM D 4935. Shielding effectiveness for both magnetic (B-field) and electric (E-field) fields was measured over a frequency range from 50 kHz to 3 GHz. SE measurements provide valuable insights into the frequency-dependent shielding properties of plastics, offering a basis for selecting appropriate materials for automotive applications to address EMC challenges.
