Dear Friends:

         I have 2 questions:

        1. about the duplication command in MEEP
        How to infinite duplicated the computational cell in one direction
in MEEP?

        I have found some CTL files in this mail-list have not contain
duplicate command.
        Is it true for MEEP to auto duplicated the computation cell in the
directions which one does not specify the PML?
        This is quite different with MPB grammar.


         2. about the definition of the spectrum
         In the example "holey waveguide" in MEEP manual ( the address:
http://ab-initio.mit.edu/wiki/index.php/Meep_Tutorial/Band_diagram%2C_resonant_modes%2C_and_transmission_in_a_holey_waveguide),
the transmission spectrum is defined as:
        T= S1/S1' (S1 and S1' has the same detector. S1 is hole structure,
S2 is without hole structure)
        But in my opinion, the transmission spectrum should define as:
        T= S1/S2 (S1 and S2 have different detector. Si is detector at
output, S2 is detector at input)


 Thanks a lot!
