Abstract Total electric field
distributions in muscle and fat tissues, due to colinear
rectangular waveguide arrays at 2.45 GHz and 915 MHz were calculated. The
effect of phase difference between incident phases on the field pattern is
shown. Phase adjustment is capable of furnishing control of either field-size
or focused field performance of the multi-element, direct contact applicator.
The tissue-applicator junction is analyzed by means of the Generalized
Scattering Matrix (GSM) of the generalized 2-port discontinuity, assuming
that the lossy homogeneous tissue is immersed in a
large waveguide. This method provides an exact calculation of multimodal
fields, as well as reflection and coupling coefficients in the apertures. Key Words: Hyperthermia,
multi-applicators, Modal Analysis |
