Communication nirkabel currently increasingly tren. The racing telecommunications operators provided the network wireless with the increasingly big speed. The data traffic through the internet and the cellular phone also increased. Without being realised, the potential data traffic caused damage to the electronics device that sensitive. The medical equipment in the hospital most was susceptible to damage resulting from penetration of the electromagnetic wave. So “ hard “ the blow that was carried out wireless? As the illustration, radio that worked to the wave 120 GHz could send the package of the data as far as 10 Gigabite (G) perdetik. The packages like the hammer pounded that member the deadly blow to the electronic device that sensitive. Beforehand was used iron-oxide to mengeblok penetration of the wave. Currently the majority of the communication device uses the high wave that could not be stifled the iron. In the speed 100 GHz, the best device of the wave silencer available in t...
