Until 2001 the phenomenon of the negative refraction has been experimentally verified first by using artificial left-handed materials realized by periodic arrays of split ring resonators (SRRs) and wire strips .

In the 1st paragraph of section 1 ¡°Until 2001 the phenomenon of the negative refraction has been experimentally verified¡± if you mean ¡°until 2001¡± (2001 is the ending point), then ¡°has been¡± has to be changed to ¡°had been¡±. If you mean ¡°since 2001¡± (2001 is the starting point) then there is no problem with ¡°has been¡±.
