Study on Propagation Characteristics of Flying Electromagnetic Toroid Pulses in Non-ideal Free Space

The propagation characteristics of flying electromagnetic toroid (FET) pulses are discussed under the condition of partial absorption boundary and the encounter of scattering bodies in the propagation path. We demonstrate that the longitudinal partial absorption boundary can lengthen the non-diffraction section of FET and FET has the structure self-repairing property. The characteristics that we demonstrate have broad application prospects in the fields of energy transmission, particle acceleration and longitudinal multistage imaging.
