| 摘要 |
The present invention relates to an apparatus for determining a dielectric function in an object. The apparatus comprises one transmit antenna ( 42 ) for transmitting microwave radiation through said object, and one receive antenna ( 43 ) for receiving the transmitted microwave radiation, one ultrasound transmitter for emitting ultrasound radiation through said object to generate a density variation in the object, means to analyse the microwave radiation transmitted through the density variation to determine the acousto-electric interaction delta in the object, and means to calculate the dielectric function in the object from the acousto-electric interaction. The invention also relates to a method for determining the dielectric function in an object. |
