摘要

在本文中，所研究的吸收器用于隔离入射电磁波的密闭区域。这样做的目的是阻止所有的微波进入密闭区域。这种吸收剂的应用是在不需要无线电和手机信号的通信领域。当电磁波击中铁氧体粒子时，电磁波的磁场部分被抵消。使用对无线电波透明的普通木材，将铁磁材料的细颗粒夹在木材中，可以阻挡无线电波，从而允许几个网络在不受干扰的情况下在附近运行。

Design and manufacture of a ferrimagnetic wave absorber for cellular phone radiations

In this article, the absorber studied is used to insulate a confined area from incident electromagnetic waves. The aim is to block all microwaves from entering the confined area. Application of such absorbers is in the communication field where radio and cell phone signals are unwanted. When an electromagnetic wave hits ferrite particles, the magnetic field part of the wave is cancelled. Using normal wood that is transparent to radio waves, with fine particles of ferrimagnetic material sandwiched in the wood, radio waves are blocked, which allow several networks to operate close by without interference.
