Method and arrangement for determining absorption rate

摘要

The invention relates to a method and an arrangement for determining the absorption rate of test subjects, for example objects, human bodies or body parts, materials, plants or the like, which test subjects are exposed to particularly high-frequency electromagnetic fields at least from one field or radiation source. According to the invention, it is proposed for the fields to be constructed in a lossless or low-loss, sealed enclosure which is a particularly good conductor of electricity, in particular a Faraday cage, and for the field power to be coupled out of the enclosure, for the coupled-out field power to be measured at least once with absence or complete covering of a test subject or with partial covering of the test subject and at least once with partial or full exposure of the test subject, and for the difference between these measured values of the coupled-out field power to be taken as equal or proportional to the power absorbed in the test subject and evaluated as a measure for the absorption rate.
