Removal of undesired wavefields related to the casing of a microwave scanner
2003
IEEE transactions on microwave theory and techniques
This paper deals with the scattered field data measured by a closed microwave scanner and discusses the removal of the effects of the metal casing as a preprocessing step before actual inversion of the data can take place. It is shown that Rayleigh's reciprocity theorem furnishes a relation between the scattered field data obtained in the closed microwave scanner and the scattered field data as if they were obtained by an open scanner without the metal casing. This relation leads to a system of
