Periodic Reporting for period 1 - PARASOL (European Doctoral Network for Safe and Sustainable by Design Electromagnetic Shielding Material)

Reporting period: 2022-11-01 to 2024-10-31

Summary of the context and overall objectives of the project

PARASOL is a Doctoral Network at the intersection of electromagnetic compatibility (EMC), materials engineering, system-safety engineering, and sustainability. It focuses on developing innovative electromagnetic (EM) shielding solutions for vehicles, addressing critical performance factors such as EM safety, weight, strength, and cost. The project integrates the Safe and Sustainable-by-Design (SSbD) approach, aiming to reduce the need for multiple prototypes by advancing design tools. PARASOL also trains professionals capable of transitioning between disciplines, fostering expertise in electronics, safety, and sustainability.
