The package contains the following programs:
	pwem2a.m - main program
	epsgg.m - routine for calculating the matrix of Fourier coefficients of dielectric function
	bz_irr1.m - routine for calculating the 'k-points' along the perimeter of irreducible Brillouin zone
	kvect2.m - routine for calculating diagonal matrices with elements(kx+Gx) and (ky+Gy), where G=(Gx,Gy) is a reciprocal lattice vector
	eigsEH.m - routine for solving the eigenvalue problems for E-pol and H-pol
	
Unpack the .zip file to an arbitrary directory, change MATLAB path and run pwem2a.m
