Abstract

Electromagnetic shielding has been enjoying greater attention recently. On one side, it is due to the electromagnetic compatibility of electric and electronic devices. On the other, it is because of the electromagnetic effect on living organisms, a human being included. We are constantly exposed to the electromagnetic field which is why it is important to raise this issue. The proposed contribution presents the results of research into the shielding of a construction object concrete towards the electromagnetic field. Shielding is defined as shielding effectiveness. Shielding effectiveness is defined by a product of reflection and absorption of the electromagnetic field. The experiment in this contribution concentrates on measurement of shielding effectiveness and reflection of the electromagnetic field. Measured object was concrete wall 120 mm thickness composed of cement and water. Based on these observables it is possible to calculate the electromagnetic absorption which is difficult to measure.

高频电磁场穿透建筑材料-混凝土墙体的实验研究

电磁屏蔽近年来受到越来越多的关注。一方面，这是由于电气和电子设备的电磁兼容性。另一方面，这是因为电磁对包括人类在内的生物的影响。我们经常暴露在电磁场中，这就是为什么提出这个问题很重要。提出的贡献介绍了对建筑物体混凝土对电磁场屏蔽的研究结果。屏蔽被定义为屏蔽效能。屏蔽效能由电磁场的反射和吸收的乘积来定义。本论文的实验集中在电磁场的屏蔽效能和反射的测量上。被测对象为水泥与水组成的混凝土墙体，厚度为120mm。根据这些观测值，可以计算出难以测量的电磁吸收。
