Outline of Final Research Achievements |
The subject of this study was to find a microwave absorption measuring device that can measure even a minute specimen and the lower limit of the specimen. Our original idea is to use the localised waves formed around the specimen, and to apply the weak-form theory for developing a suitable microwave absorption analysis method. It was found that a reliable measurement is possible even if the amount of specimen is suppressed to about 20 microliters provided that a material with a specific permittivity of about 2 is filled in the cavity of the planar type and the coaxial type waveguides. Furthermore, by applying the weak form theory, we have developed a basic equation that reflects the influence of the resonance device on the metal wall and a method for detecting material properties using this equation.
