[MPB-discuss] scaling properties of dielectric constant

2007-07-20 Thread Philipp Waibel
Dear all, I'm wondering about an easy triangular lattice of holes-calculation. I simulated that lattice with radius/lattice constant=0.45 once with epsilon=11.4 (like e.g. in the book of Joannopoulos) and once with epsilon=2.45. There appeared a bandgap in tm-polarization between band 2 and 3

[MPB-discuss] Fwd: scaling properties of dielectric constant

2007-07-20 Thread edvnagesh
Dear Mr. Philipp, You missed one point in scaling property. While one corresponds to length (radius/lattice spacing), the other corresponds to the dielectric contrast. When you changed the dielectric constant from 11.4 to 2.45, obviously, the dielectric contrast got changed and that is the

When i tried to use ./configure for MPB, the following error message appeared. I've installed g77, do i need to install f77 as well to proceed with MPB installation? I'm quite new to this, someone help me please... [EMAIL PROTECTED] mpb-1.4.2]# ./configure checking for vendor f77 to be used
