Feise, MichaelKivshar, Yuri2015-12-130375-9601http://hdl.handle.net/1885/82806We study numerically, by means of the pseudospectral time-domain method, the unique features of imaging by a flat lens made of a left-handed metamaterial that possesses the property of negative refraction. We confirm the earlier finding that a left-handed flat lens can provide near-perfect imaging of a point source and a pair of point sources with clear evidence of sub-wavelength resolution. We illustrate the limitation of the resolution in the time-integrated image due to the presence of surface waves.Keywords: article; device; imaging; refraction index; spectral sensitivity; theoretical model Double-negative material; Image resolution; Left-handed material; Negative refractive index; Surface waves200410.1016/j.physleta.2004.11.0312015-12-11
