Integrating magnetically coupled technologies into electronic designs can introduce uncontrolled magnetic fields that cause functional disturbances and electromagnetic compatibility (EMC) issues. Selecting the right shielding material – and understanding how it behaves across frequency – is critical for both effective interference suppression and efficient energy transfer.
This Support Note examines the behavior and performance of WE-FNCS (Flexible Nanocrystalline Sheets) in two distinct application contexts: magnetic shielding and inductive wireless power transfer (WPT). The document covers the underlying theoretical principles, presents a controlled laboratory test setup, and provides comparative measurement results against alternative materials including mu-metal alloys, flexible absorber sheets, and flexible sintered ferrite sheets.
Reading this application note will help with understanding how WE-FNCS complex permeability (μ′ and μ″) determines shielding effectiveness and energy-transfer efficiency across the 200 kHz – 1 MHz range. Discover how WE-FNCS are ideal as temporary diagnostic tools during PCB development and EMC debugging to identify dominant coupling mechanisms without board changes.
