🚀 Exploring Electromagnetic Wave Propagation Beyond the Speed of Light 🌟

Описание: In this YouTube short, we demonstrate an FDTD (Finite Difference Time Domain) simulation where an electromagnetic line source moves faster than the speed of light. Interestingly, this analysis does not implement the traditional Lorentz transformation of space and time, but instead follows a similar approach to that of Heaviside, who solved this scenario using Maxwell's equations analytically.

Just like Heaviside's work (O. Heaviside, “Electromagnetic waves, the propagation of potentials, and the electromagnetic effects of a moving charge,” The Electrician, vol. 22, pp. 147–148, 1888), we can observe the formation of a shockwave cone in our simulation, with the angle given by Mach's formula:
θ_Mach = arcsin(c/v),
where c is the speed of light, and v is the speed of the moving source.

The video offers a fascinating glimpse into this phenomenon, showing how wavefronts accumulate to form a shockwave and providing a fresh perspective on wave propagation in faster-than-light scenarios.
