| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In recent years, small and high speed operating electronic devices have been widely used. As a result, undesired electromagnetic wave radiated from the electronic devices results in a serious problem. It is well-known that a source reconstruction technique is helpful in order to find source location of the undesired electromagnetic waves. On the other hand, source reconstruction of the devices is difficult because of complicated or unknown geometry of the source and its ill-conditioned nature. In this report, a source reconstruction method which is based on the eigenmode current of hypothetical sources is proposed. The proposed method is applicable to reconstruction of source whose geometry is unknown or complicated because hypothetical sources are allocated over entire region of the source to be reconstructed. The number of eigenmode currents used for source reconstruction is reduced in order to alleviate ill-conditioned nature of source reconstruction.Performance of the proposed method is demonstrated via numerical simulation. | |
