Design and construction of a microwave magnetization/demagnetization system for geomagnetic paleointensity determination

为应用微波LTD-DHT-Shaw方法，设计并建造了微波磁化/退磁系统样机。该系统使用17.3-18.1 GHz微波。该系统最重要的组成部分是一个谐振腔，它是测试和没有岩石样品。对于没有样品的测试，识别出尖锐的微波吸收，而对于有样品的测试，观察到迟钝的吸收。为了实际使用该系统，应减少样本量。

A prototype microwave magnetization/demagnetization system have been designed and constructed for an application of the microwave LTD-DHT Shaw method. The system use 17.3-18.1 GHz microwaves. The most important component of the system is a resonant cavity and it is tested with and without a rock sample. Sharp microwave absorption is recognized for the test without the sample, whereas a dull absorption is observed for the test with the sample. Towards the practical use of the system, sample size should be reduced.
