Radiator: Polarizarea

The effect of polarization or wave overlapping can often be seen in nature. Particularly impressive in the case of high water at such places which are situated at the intersection point of 2 rivers. Because 2 high water waves meet simultaneously each other at the intersection point, special high water dangers result as an effect of wave overlapping. If the high water waves arrive in sequence, there are two separate high water maximum and the high water remains in total lower.

So achieved Pausau in Germany, where the rivers Inn and Danube come together, during the last year high water on the 14th January the high water wave of the Inn and three days later the high water wave of Danube. The waves therefore, arrived separated, which led to a comparably low resultant high water wave.

How ever, this should look fundamentally different only two weeks later. This time, at the 2nd February, the high water waves of Inn and Danube achieved almost simultaneously in Pausau so that a resultant high water wave caused big damages.

	Figure 4: Heat radiation from ordinary electrical heater Figure 5: Polarized heat radiation from electro-ceramic radiator	Technically spoken one calls such waves with no time difference between wave maximum as in phase or overlapped or just polarized. How to above example explains, achieve two or more polarized waves a greater effect in the room they go through because the wave maximum is achieved at same time. This expresses itself in the vectorial sum of the energie, the resultant. This means in the other extreme that two waves in opposite phase (the wave maximum of a wave meets to the wave minimum of an other wave) erase the resultant which leads in this case to a minimum effect. With this, the high efficiency of our electro-ceramic radiators can be explained, because they transfer the heat radiation polarized into the room.
