The effect slot positions and dimensions have on the size of the ablation zone, reflected power and highest temperature reached by microwave antennas in a hepatic tissue phantom is analyzed with COMSOL Multiphysics. Two antenna configurations are analyzed, coaxial double slot and single slot with choke while taking into account antenna heating.
This paper studies the effects of foam on the transmission and reflection of microwave signals for radar instruments used in level measurement. A test scenario consisting of a periodic two-dimensional wet monodispersed foam layer at the separation boundary between two media was modeled. The bubble size, number of layers and material properties were parametrically controlled to cover a wide range of...
The paper presents a study of how improper installation procedures and geometry modifications affect Non-Contacting Radar (NCR) antenna emission spectrums. COMSOL Multiphysics was used to simulate the most common issues found in the process industry.
