Nearfield subwavelength imaging based on negative refraction in wavelike twodimensional photonic crystals within infared band. The adopted rectangular isofrequency surface results in the inhomogereity of wavelike twodimensional photonic crystal unavoidably, so the imaging is confined in the nearfield region. For the lack of the circularshaped isofrequency surface in photonic crystal matching that of the incident medium, farfield imaging based on negative refraction is unavailable in wavelike twodimensional photonic crystal. The finitedifference timedomain method is used to simulate the nearfield imaging in wavelike twodimensional photonic crystal of different thickness. The resolution of 0.28λ is achieved for single point source when the thickness of photonic crystal is twice of lattice constant. The resolution will gradually degrade as the source moves beyond the nearfield domain. Meanwhile, the image is strongly confined in the nearfield region on the other side of photonic crystal in spite of the change of source position and photonic crystal thickness. In order to further demonstrate the subwavelength imaging ability of wavelike twodimensional photonic crystal, double sources are used. Resolution of 0.35λ is obtained, but the imaging quality depends on the thickness of photonic crystal greately.
