Abstract:
1. An electromagnetic wave analysis apparatus for examining an effect on communication signals transmitted and received via an antenna of unwanted radiation noise generated from a circuit board of electronic equipment that transmits and receives communication signals via the antenna, the electromagnetic wave analysis apparatus comprising: an antenna electromagnetic field distribution input portion that inputs antenna electromagnetic field distribution data indicating a distribution of an antenna electromagnetic field that is a magnetic field component or an electric field component of electromagnetic waves that are the communication signals transmitted and received via the antenna; a board near electromagnetic field distribution input portion that inputs board near electromagnetic field distribution data indicating a distribution of either or both of an electric field component and a magnetic field component of a board near electromagnetic field that is unwanted radiation noise radiated from the circuit board of the electronic equipment as a result of operation of the electronic equipment; and a correlation value generator that generates a distribution of correlation values showing a correlation between the antenna electromagnetic field and the board near electromagnetic field based on the antenna electromagnetic field distribution data and the board near electromagnetic field distribution data.
