Modélisation de la propagation dans une structure fermée surdimensionnée

Abstract : The propagation of an electromagnetic wave in closed structures led to numerous applications ranging from the characterization of materials in resonating cavities to the measurements using pregnant reverberant EMF. We created models to study the existence of electromagnetic waves in large closed structures. There are two ways of excitation in such structures. One of these methods is based on continuous excitation with specific resonant modes, which has a variety of applications. The second method consists of a pulsed excitation similar to the impulse wave radar. This excitation provides other information. The structures studied were closed by perfectly conducting walls and the electromagnetic wave was generated in the structure using dipole antennas. The dimensions (length, width and height) were always much larger than the wavelength.
