Arrangement for producing desired distributions of electromagnetic waves in process systems achieves Eigen mode mix with transfer part calculated by scattering matrix formalism

摘要

The arrangement has a desired field distribution divided into the Eigen modes of the applicator (3) cross-section. The Eigen mode mix is achieved with a transfer part (2) calculated with the aid of a scattering matrix formalism. The desired field distribution is homogeneous in a rectangular cross-section and the mode mixture is achieved with a Fourier decomposition.
