摘要: It is shown that unlike a gas plasma or an electron in metal, ionized clustered material (“cluster plasma”) permits propagation below the cut-off of electromagnetic (EM) waves whose phase velocity close to but speed light. Its unique properties allow variety applications, including direct acceleration particles with its EM fields and matching high harmonic generation (HHG). The particle-in-cell simulation demonstrates new optical mode, cluster mode.
