The ouput is the TE/TM band structure (first five bands) along pricipal directions (G-X-M-G) of a square-lattice photonic crystal with unit cell consisting of a substrate of "epb" relative permittivity with circular rods(holes) of "epa" relative permittivity and radius "r". Usage is SharifPWE_BZplot(N,RES,r,epa,epb) N: N in PWE algorithm (number at which the summations are truncated) RES: number of the divisions on every side of BZ#1 r: normalized radius of the circle of holes/rods (0<r<0.5) epa: relative permittivity of holes/rods epb: relative permittivity of the substrate Written by Amir Hosseini for the Course Photonic Crystals (C) Copyright 2005 School of Electrical Engineering Sharif University of Technology All Rights Reserved

Incremental Conductance: In the incremental conductance algorithm, we find the derivative of PV output power with respect to output voltage. The dP/dV is evaluated and the algorithm keeps checking this value and changes the duty cycle such that dP/dV=- I/V = 0. This is the point at which maximum power is transferred. If dP/dV is greater than zero, it means the PV is operating to the left of the MPP. If dP/dV is less than zero, it means the PV is operating to the right of the MPP. This method holds an advantage over the perturb and observe method since it is fast and does not oscillate around MPP. However, the method could experience instability due the involvement of the derivative.
