Recently, in celluar mobile communications, the number of customers who use cellular phone indoors is rapidly increasing. Many examinations have been reported about the outdoor propagation loss characteristic, and the propagation model and the presuming method are standardized. On the other hand, althought the presumed type based on an experiment has been proposed about the propagation loss characteristic, examination of the physical model which can take into consideration the size of a passage and number of passersby in detail is carried out and the performance of information processing technique is increasing by the progress of the computers which make easy the analysis of electromagnetic wave for simulation. In order to resolve the issues of the design of the electromagnetic devices, the development of excellent algorithms has been desired. The numerical technique to solve the EM problem such as FEM, Method of Moment, FDTD method and so on has been proposed. Inthis report, the multigrid-moment method is applied to the scattering problem of EM wave by cylindrical object in orfer to speed up CPU time.
