Abstract
It is necessary to conquer various technical subject, such as development of material, electromagnetic field simulation technology, and near electromagnetic field measurement technology, in order to acquire the effective absorption characteristic in near electromagnetic field. In this announcement, it introduces about the example of examination of the effect of EM absorption material though [case/where EM absorption material has been arranged the inside of a case, and on a transmmision line, or the main part of a cellular phone] simulation technology (the FDTD method) or an experiment.
