Examples
Exemple :
The figure below illustrates three cases:
Case A: radiation mass is determined by a presence of a screen in the "continuity" of an oscillating piston. Radiation resistance is due to the dispersion of the energy into a half-sphere.
Case B: radiation mass is determined by the absence of a screen in the "continuity" of the oscillating piston. Radiation resistance is due to the dispersion of the energy into a sphere.
Case C: radiation mass is determined by a presence of an obstacle in front of a piston and by the absence of screen in the continuity of an oscillating piston. The radiation resistance is the same as that of case B (dispersion into a sphere).
