Claim Text:
1. An apparatus for analyzing a distribution of electromagnetic waves in a radio wave system, the apparatus comprising: an input unit configured to apply a reference electrostatic potential to an inside of a 4-port transverse electromagnetic (TEM) cell in which electronic devices are located; a calculation unit configured to calculate electrostatic potentials inside the 4-port TEM cell using a mode matching scheme, wherein the calculation unit divides the inside of the 4-port TEM cell into a plurality of regions according to a septum included in the inside of the 4-port TEM cell to calculate the electrostatic potentials in each region, the calculation unit calculates discrete mode coefficients and calculates the electrostatic potentials in each region using the discrete mode coefficients, the calculation unit calculates the electrostatic potentials in each region in consideration of a Dirichlet boundary condition and a Neumann boundary condition at a point at which each region contacts each other, and wherein the calculation unit calculates the electrostatic potentials in each region in consideration of a continuity of electrostatic potentials and a continuity of y-axis variations at a point at which each region contacts each other; an analysis unit configured to analyze the distribution of electromagnetic waves inside the 4-port TEM cell through the electrostatic potentials inside the 4-port TEM cell; and an output unit configured to output the distribution of electromagnetic waves inside the 4-port TEM cell.
