Abstract

Abstract

En 中文
• A design optimization method for OSSC embedded in nanocrystalline magnetic shielding helmet NMSH is proposed. • A TFM-based OSSC forward current density model takes NMSH magnetic features as core boundaries. • MOPSO optimizes field uniformity and attenuation for high-performance simple single-layer coils. • Designed OSSC has 0.94% uniformity error, restrains stray field for wearable lightweight MEG systems.
