In daily life we make use of a lot of wireless technologies which significantly simplify our work, communication and household jobs. As an example we can use smart thermostats from a distance. Those devices are able to connect with the heating from a distance. Or the children make use of the WiFi in the house to play video games on their mobile phones while in the past this usually only happened with a landline in the ground. Despite the many advantages which wireless life has to offer there are some disadvantages where most people don’t have to deal with unless it’s a very exclusive case.

For some companies the microwaves being emitted by wireless connection are a huge source of noise for those companies. In case they’re developing products that themselves are dependent on radio- or microwaves which are picked up by sensitive antennas it is very hard to test these kind of products in an environment bombarded with high frequency non-ionizing radiation. When you want to know exactly what could go wrong in information transfer via electromagnetic radiation then you would like the signal to be received in the most pure way.

Microwave absorbers for walls and surfaces

Such innovative enterprises benefit from high quality radiowave or microwave absorbers. The walls in a test chamber could be equipped with long points made of foam or polystyrene. The form of these points is of exceptional importance. A high quality productof this type can be found here: Pyramidal absorber – DMAS. The surfaces bounce of the radiowaves and microwaves under a precise angle what causes it to bounce off this form until most of it is absorbed and the energy is lost. A small part of the electromagnetic radiation will reflect back to the source, however this is insignificant in comparison to the reflections without absorbing material.

Absorption materials for extreme environments

There are two types of radio- and microwave absorbing material. At first there is a foam that is used quite often. Second there is also polystyrene which has certain advantageous properties compared to the outdated foam. For example absorbing products made of polystyrene won’t release any carbon particles to the environment. Those types of particles usually release from the foam because of the effects of time. The closed off cell structure of the new material doesn’t have this problem. The carbon particles stay put because of this enclosed structure. Especially laboratories which need extremely clean environments to operate in this property are required for microwave absorbers.

Electromagnetic radiation in everyday life

Most people won’t experience much difficulty because of pollution by electromagnetic radiation. Household appliances are known to send out such radiation since the necessary supply of electricity from the socket will cause a large difference in electromagnetism in the surrounding area. Usually the cables are properly encapsulated what reducing this effect to a minimum. But in some cases one can experience the consequences of such device in the house. It is for example possible to make the speakerset crackle when you keep your mobile phone next to it. In general one should’nt worry too much about these kind of effects in the house.
