Abstract
In this paper calculations of the electric field distribution are presented with regard to the development of new plasma sources with
bifocal structures. These structures facilitate the separation of microwave emission and microwave concentration. Similar to a focusing
optical mirror this approach leads to a concentration of wave energy in a focus region where the plasma can be ignited and
maintained.
The validity of this approach for microwaves at 2.45 GHz in dependence on geometry and configuration of the structure and the
possibility of a linear extension was examined through the following steps: starting with a rectangular waveguide that was
elliptically bulged to a bifocal structure in several scales, the same structure was stacked with a passageway in between. A complete
removal of inner partitions was examined and finally the influence of a plasma-like absorber in the focus region. The result is a
microwave concentration near the focus points and the structures are linearly extendable without bothering crosstalk or other side
effects.
