The tilt angle 45° in six fold symmetry, transform the Gaussian edge-void into oscillatory waves. These waves start to appear with small amplitudes and they spread in all directions while enhancing their strength. The meanwhile, the distorted edge-void with decreasing in strength drags towards the cathode end carrying the all package of subsidiary oscillations. This resembles the light source making translational motion while constantly emanating light waves in all directions. There is one difference, the source strength for the present case increases with time. This is a good example for the behavior of a completely regenerative nonlinear system, where the source even appealingly decaying in size itself (better to say the broadening in space), still it soaks constant energy from the blowing electron winds.
