文摘In 1996,Pendry proposed plasma-like oscillation(PLO)in the long-metallic-strip(LMS)array.With the ability of permittivity reduction,it is effective for negative refractive index and electromagnetic(EM)transparency,thereby promoting the development of metamaterials.In this manuscript,we discover a novel magnetic response in the LMS array,which is excited at high frequencies with TE polarization incident at large angles(≥60°).With similar currents to PLO,the magnetic response has EM characteristics similar to those of PLO,where the most typical is the permittivity reduction.Thus,it is called plasma-like-like oscillation(PLLO)here.The discovery is well verified by the monitored induced currents,the magnetic field,the spectrum comparison,and the extracted EM parameters.The prototypes are designed,fabricated,and measured,where the measured results are basically consistent with the simulated ones.With a similar permittivity reduction to PLO,PLLO would provide new ideas for left-handed materials and EM windows.
