Abstract: The effect: the interaction of every solid with electromagnetic field induces an alternating potential difference with the same frequency as the frequency of the incident field.

 

Experimentally, the potential difference between the irradiated sample and the common electric ground of the system was measured. An important feature of the SPCE is its significant dependence on the specific properties of the irradiated sample. This fact reveals vast opportunities for rapid and contactless analysis of solids, liquids and gases.

 

In contrast to other similar effects, the SPCE is characteristic of all kinds of solids and this makes it very interesting from scientific as well as from practical point of view.

 

Keywords: surfaces, fluids, level, chemical composition
