The design of analysis and test platform for electromagnetic wave energy security
Abstract
The underground metal structure in the radiation field of the radio frequency antenna can be equivalent to the receiving antenna.The energy of electromagnetic wave focused on the metal structure will be released in the form of discharge spark under scratch condition.At present, there is no testing method and experimental equipment to measure the discharge spark caused by electromagnetic wave energy.In order to solve this problem, this paper develops a testing platform for electromagnetic wave energy security analysis.According to the different ways of coupling electromagnetic wave energy to metal structure, the platform designs three kinds of devices:radiation field(RF) coupling energy test, electromagnetic wave energy magnetic resonance coupling power test and electromagnetic wave energy discharge spark experiment.On this basis, the spark power experiment of the RF signal source under scratch condition was carried out.The experimental results show that when the output power of the signal source is less than 4.1 W, the spark caused by the energy of the RF electromagnetic wave would not ignite the gas.
