ABSTRACT:
The present invention relates to an electromagnetically-countered system including at least one wave source irradiating harmful electromagnetic waves and at least one counter unit emitting counter electromagnetic waves for countering the harmful waves by such counter waves. More particularly, the present invention relates to generic counter units of electromagnetically-countered systems and to various mechanisms for countering the harmful waves by the counter units such as, e.g., by matching configurations of the counter units with those of the wave sources, matching shapes of such counter waves with shapes of the harmful waves, and the like. The present invention also relates to various methods of countering the harmful waves with the counter waves by such source matching or wave matching and various methods of providing the counter units as well as counter waves. The present invention further relates to various processes for providing such systems, such counter units thereof, and the like. The present invention relates to various electric and/or magnetic shields which may be used alone or in conjunction with such counter units to minimize irradiation of the harmful waves from the system.
