Electromagnetic wave propagates in 3D photonic time crystal and 3D photonic non-time crystal. (a) Electric field propagates in 3D photonic time crystal, seeing in z-direction, ε(t) = 5 + sin ωt. (b) Electric field propagates in 3D photonic time crystal, seeing in y-direction, ε(t) = 5 + sin ωt. (c) Electric field propagates in 3D photonic non-time crystal, seeing in z-direction, ε(t) = 6. (d) Electric field propagates in 3D photonic non-time crystal, seeing in y-direction, ε(t) = 6. (e) Electric field propagates in 3D photonic non-time crystal, seeing in z-direction, ε(t) = 4. (f) Electric field propagates in 3D photonic non-time crystal, seeing in y-direction, ε(t) = 4. The propagation time is at the time step 500.
