A Novel Structure for Optical Channel Drop Filter using Two-Dimensional Photonic Crystals with Square Lattice
In the present paper a novel structure for optical channel drop filter (CDF) based on photonic crystal ring resonator with circular core has been proposed. In order to design the proposed CDF, the plan wave expansion (PWE) method is applied for calculation of band structure and photonic band gap while the transmission characteristics of proposed CDF have been calculated using the finite differe...
متن کاملMagnetic properties of the two-dimensional Heisenberg model on a triangular lattice
The spin Green’s function of the antiferromagnetic Heisenberg model on a triangular lattice is calculated using Mori’s projection operator technique. At T = 0 the spin excitation spectrum is shown to have gaps at the wave vectors of the classical Néel ordering. This points to the absence of the antiferromagnetic long-range order in the ground state. The calculated spin correlation on the neighb...
متن کاملMagnetic vortex dynamics in a two-dimensional square lattice of ferromagnetic nanodisks
The dynamics of magnetostatically coupled vortices in ferromagnetic two-dimensional (2D) nanodisk arrays is theoretically investigated using the rigid vortex model and Thiele’s equation whereby the circular motion with the lowest energy for each vortex core is described. We present here dispersion relations and density of states for eigenfrequencies of coherently rotating vortices with ordered ...
متن کاملFolding transitions of the square – diagonal two – dimensional lattice ∗
The phase diagram of a vertex model introduced by P. Di Francesco (Nucl. Phys. B 525, 507 1998) representing the configurations of a square lattice which can fold with different bending energies along the main axes and the diagonals has been studied by Cluster Variation Method. A very rich structure with partially and completely folded phases, different disordered phases and a flat phase is fou...
