New detailed understanding of the mechanism of radiation in interconnect problems

Electromagnetic radiations from parasitic structures such as electronic interconnections are very difficult to diagnose because the ability to identify the specific sources are missing. Mainly, the source of radiations cannot be identified separately. Here, the partial element equivalent circuit (PEEC) method is extended to diagnose the radiation and its distribution. For the first time we identify the individual sources of radiation and the equivalence circuits for the sources. The proposed approach can be applied to find the radiation for electromagnetic interference (EMI) from a wide variety of structures.
