Research of Electromagnetic Interference Shielding Materials and Test Techniques

With the severe electromagnetic pollution and microwave leakage, electromagnetic interference (EMI) shielding materials as a representative role of electromagnetic protection materials have been widely used in military and civilian electronic equipment. At present, metallic EMI shielding materials benefiting from their intrinsic electromagnetic properties, coated EMI shielding materials combining a highly conductive layer with an insulating substrate and EMI shielding fabrics with excellent flexibility have been able to be mass-produced. More and more new EMI shielding materials that are flexible, transparent, and deformable are invented to meet the new requirements of the shielding market for versatility, environmental applicability, and ease of processing and assembly. EMI shielding test technology also presents a diversified and refined development trend based on existing near-field and far-field test technologies.
