In order to estimate the level of the electromagnetic field produced by telecommunication systems, different computational techniques can be employed whose complexity depends on the accuracy of the final results. In this paper, we present the validation of a code based on the method of moments that allows us to analyse the electromagnetic field emitted by radio-communication systems operating at medium frequencies. The method is able to provide an accurate estimate of the levels of electromagnetic field produced by this type of device and, consequently, it can be used as a method for verifying the compliance of the system with the safe exposure level regulations and population protection laws. Some numerical and experimental results are shown relevant to an amplitude modulated (AM) radio transmitter, together with the results of a forthcoming system that will be operative in the near future.
为了估计电信系统产生的电磁场水平，可以采用不同的计算技术，其复杂度取决于最终结果的准确性。在本文中，我们展示了基于矩量法的代码的验证情况，该代码使我们能够分析工作在中频的无线电通信系统发射的电磁场。该方法能够准确估计此类设备产生的电磁场水平，因此，它可以用作一种方法来验证系统是否符合安全暴露水平规定和人群保护法律。展示了一些与调幅（AM）无线电发射机相关的数值和实验结果，以及一个即将在不久的将来投入使用的系统的结果。
