Permalloy mesh is a great solution in providing shielding from the variable frequency electric and magnetic waves. The square woven mesh acts as an equivalent sheet impedance operator. Its effectiveness in the plane wave shielding prevents the coupling effect between antennas in either side of the planar mesh. The extent of shielding provided is based on the geometry of enclosure, mesh size and wire radius.
Screening solutions for windows, clothes, screening tents, medical applications with damping about 50 dB.
Protective screening mesh is utilized for security against magnetic field in frequencies ranging from 100MHz to 10GHz. It is permeable to air, rot resistant and frost proof. It is also utilized for shielding against radiation from radio, TV, Microwave, Bluetooth and other similar sources.
The magnetic shielding mesh is also rolled and can be utilized to replace standard reinforcement mesh to save money. It is specifically manufactured for easy handling even by an amateur.
