Magnetic Thin Film Absorbing Material Designed For RFID Label
Magnetic Thin Film Absorbing Material designed for RFID labels is a specialized EMI absorption solution developed to improve reading performance and signal stability in RFID systems. By integrating high-permeability magnetic fillers into an ultra-thin flexible film, this material effectively absorbs unwanted electromagnetic interference and suppresses detuning effects caused by metal surfaces or nearby electronic components. Unlike conventional shielding layers that reflect RF energy, magnetic thin film absorbers convert electromagnetic waves into thermal energy, enabling cleaner signal transmission and enhanced tag sensitivity.
