Prediction and assessment method for two-lead transmission line terminal response

Abstract

The invention discloses a prediction and assessment method for a two-lead transmission line terminal response in a non-analytic distribution source. The method comprises the steps of measuring physical parameters of leads; geometrically discretizing a transmission line; measuring geometric parameters of the transmission line; measuring electric parameters of the transmission line; and finally making a calculation to obtain an induced voltage and an induced current of a parallel or non-parallel two-lead transmission line terminal. In an assessment process, a specific analytic expression of an additional excitation source does not need to be known and only discretized data, distributed along the leads, of an excitation field needs to be known. According to the method, computing errors caused by reasons such as energy loss and the like in an irradiation process of the distribution source do not need to be considered, the transmission line is slightly transformed, the measurement data amount is relatively small, and the accuracy of a measurement result is relatively high; in a measurement process, other additional circuits do not need to be carried, so that the errors caused by additional devices are relatively small; and the method is suitable for various additional electromagnetic field irradiation and is simple in operation and easy to realize.

Description

technical field [0001] The invention relates to a method for evaluating the response of a wire terminal, in particular to a method for predicting and evaluating the response of a double-conductor transmission line terminal. Background technique [0002] With the rapid development of modern electronic technology, in many electronic devices, the integration of circuits is getting higher and higher, the size of the devices is getting smaller and smaller, and the internal structure is becoming more and more complex. The electromagnetic signal strength frequency bands used are different. At the same time, with the sharp increase in the types of external radiation interference sources, the electromagnetic environment in which modern electronic information equipment works is becoming more and more complex, often manifested as extremely high spatial density, difficult to estimate in the time domain, and a wide range of bands in the frequency domain. Types are increasingly diverse. ...

Problems solved by technology

However, the excitation source model involved in practical engineering applications is usually non-analytic, and often only the discretized distribution of the excitation source along the wire can be obtained. Therefore, it is urgent to propose a method that can realize the terminal response of the double-conductor transmission line under the non-analytic distributed source. predictive assessment of
