Comparison of reverberation chamber shapes inspired from chaotic cavities

Abstract : Using the knowledge gained from the wave chaos theory, we present simple shapes of resonant cavities obtained by inserting metallic hemispheres or caps on the walls of a parallelepiped-shaped cavity. The presented simulation results show a significant improvement of the field statistical properties when the number of hemispheres or caps increases, and the comparison with a classical reverberation chamber geometry shows an improved homogeneity and isotropy can be attained using these new proposed shapes.
