The use of mobile phone can be obligatorily forbidden through cellphone jammer to guarantee the safety of the above places

This cell phone jammer company has led the entire cell phone jammer industry
Therefore, increase the shielding effectiveness of the method is: high permeability surface coating of high conductivity material;
b). Low-frequency magnetic field shielding using high permeability magnetic alloy composition to short-circuit magnetic field lines;
c). Magnetic shielding performance and the material thickness, permeability is proportional to the size and inversely proportional to shield other;
d). Magnetic field is strong, to use the multi-layer shielded to prevent magnetic saturation;
e). Machining of high permeability will reduce the shielding effectiveness of materials, heat treatment after resume;The use of mobile phone can be obligatorily forbidden through cell phone jammer to guarantee the safety of the above places.
f). High permeability material permeability and frequency, is generally used only below 1 kHz;
g). High permeability material plus a two special requirements, according to the manufacturer's specifications for processing, it is best to use the factory processed products.

Scientific exploration and knowledge innovation and technology on the principle of electromagnetic shielding of
Abstract This paper describes the electromagnetic shielding. Keywords: electromagnetic shielding CLC: O4 1 Introduction With the development of electronic technology, people living in the production of electrical and electronic equipment used in more and more cars, electronics, communications, computers and electrical equipment into a large number of families, electromagnetic wave radiated electromagnetic energy at an annual rate of 7% -14% increase, electromagnetic environmental pollution is getting worse. mobile phone jammer can effectively shield microwave signals between the cell tower and the cell phone. On the other hand, electrical and electronic equipment to increase the sensitivity of the external electromagnetic environment, electrical and electronic equipment due to the increasingly digital, highly integrated, small to quantify the signal level to meet their high-speed, light weight and small size requirements, highly vulnerable to external electromagnetic interference to malfunction, leading to serious consequences. For these reasons, there is growing emphasis on electronic products, electromagnetic compatibility (EMC) electromagnetic shielding technology was more widely. cell phone jammer applies the brand-new imported original devices.Communications products, medical equipment, household appliances, in particular to prevent information leakage and enhanced anti-jamming of military equipment, the need for electromagnetic shielding device to reduce the radiation environment on the device or devices interfere with the environmental electromagnetic pollution electromagnetic shielding is EMC Technology is one of the main measures,
