  • Apparatus and method for analyzing distribution of electromagnetic wave in radio wave system
    Patent number: 9377494
    Abstract: Disclosed are an apparatus and a method for analyzing a distribution of electromagnetic waves using a 4-port transverse electromagnetic (TEM) cell in a radio wave system. The apparatus for analyzing a distribution of electromagnetic waves in a radio wave system includes: 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; 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.

  • APPARATUS AND METHOD FOR GENERATING ANALYSIS ALGORITHM OF ELECTROMAGNETIC FIELD GENERATOR
    Publication number: 20130006553
    Abstract: An analysis algorithm generation apparatus of an electromagnetic field generator includes: a value inputting unit for receiving information on a TEM cell or GTEM cell; and an algorithm generating unit for generating an algorithm to analyze a TEM mode in a cross sectional structure of the GTEM cell or a tapered section of the TEM cell by using an associated Legendre function and a mode-matching method based on the information transmitted from the value inputting unit. The algorithm generating unit analyzes the TEM mode by dividing a space into four (left, right, upper and lower) regions, the space existing between an inner electrode and an outer wall of the cross sectional structure of the GTEM cell or the tapered section of the TEM cell.
