  We realize a suppression of an electromagnetically induced transparency (EIT)
like transmission in a metasurface induced by a local electric field that is
strongly enhanced based on two approaches: squeezing of electromagnetic energy
in resonant metasurfaces and enhancement of electromagnetic energy density
associated with a low group velocity. The EIT-like metasurface consists of a
pair of radiatively coupled cut-wire resonators, and it can effect both field
enhancement approaches simultaneously. The strongly enhanced local electric
field generates an air discharge plasma at either of the gaps of the cut-wire
resonators, which causes the EIT-like metasurface to change into two kinds of
Lorentz type metasurfaces.
