Prog. Electromagn. Res. M, vol. 49, 2016
This paper describes the analysis of triangular and square lattice 2d plasma-metal photonic crystal placed in external magnetic field. The simulation is done using FDTD method. Novel grid structure is used in this paper for FDTD simulation. Another eye catching feature is use of modified unit cell for triangular lattice.

PHOTONIC AND OMNIDIRECTIONAL BAND GAP ENGINEERING IN ONE-DIMENSIONAL PHOTONIC CRYSTALS CONSISTING OF LINEARLY GRADED INDEX MATERIAL
MAY 2016
B. K. Singh, M. K. Chaudhari, and P. C. Pandey
J. Light. Technol., vol. 34, no. 10, pp. 2431–2438, May 2016
In this paper Engineering of photonic and omnidirectional band gaps is demonstrated theoretically in one-dimensional photonic crystals (1D-PCs) containing linearly graded and constant refractive index materials. Photonic bandgaps can be controlled by contrast of refractive index as well as grading profile.

TUNABLE PHOTONIC DEFECT MODES IN ONE-DIMENSIONAL PHOTONIC CRYSTALS CONTAINING EXPONENTIALLY AND LINEARLY GRADED INDEX DEFECT
AUGUST 2016
B. K. Singh, S. Tiwari, M. K. Chaudhari, and P. C. Pandey
Opt. - Int. J. Light Electron Opt., vol. 127, no. 16, pp. 6452–6462, Aug. 2016
This paper described the analysis of tunable defect modes with liner and exponentially graded refractive index profiles. The grading profiles in the defect layer affect the frequency and intensity of photonic defect modes.
