Lorentz invariance of absorption and extinction cross sections of a uniformly moving object
Lorentz invariance of absorption and extinction cross sections of a uniformly moving object
The energy absorption and energy extinction cross sections of an object in uniform translational motion in free space are Lorentz invariant, but the total energy scattering cross section is not. Indeed, the forward-scattering theorem holds true for comoving observers but not for other inertial observers. If a pulsed plane wave …
