[Meep-discuss] diffraction limit

dear all users I am a physics student and studied Fourier optics recently. I know what is diffraction limited lens and diffraction limits. But I don’t know why we cannot confine light in a region smaller than the light wavelength for traditional optical waveguides. Please guide me. Thanks in advan

[Meep-discuss] error in compiling libctl3.2.2

Dear professor I want to install libctl on my note book core I 7 and graphical AMD my operating system is ubuntu 14.04 64 bit AMD I have installed guile 2.0 and guile dev through software center I run "./configure GUILE=/usr/bin/guile GUILE_CONFIG=/usr/bin/guile-config" but when I run make this er

[Meep-discuss] hdf5-parallel

hi all users I want to install hdf5-parallel I used these commands ./configure --enable-parallel make make install . then a hdf5 file was made in hdf5-1.8.8 and I copied them(bin, include,share lib) into /usr/local/lib in the lib directory these files exist: libhdf5.a libhdf5_hl.a libhdf5_hl.la

Re: [Meep-discuss] meep-discuss Digest, Vol 70, Issue 11

hi. the unit in MEEP and in MPB is the same. in meep and mpb , the period is 1 the each frequency that you achieved form mpb, you can use it to meep directly . for example if .2 is an eigen frequency of a pc that you achieved it form mpb, you can set the frequency of the source to .2 in the range o

[Meep-discuss] a question about minus Q factor

hi every one I have written a ctl file to calculate Q factor in a pc cavity . I want to calculate TE mode in the cavity and I used Ey for src component . but harminv give a minus q factor. what is wrong? my cod is :(reset-meep) (define-param diel_hole 1);dielectric constant of the holes (define-pa

[Meep-discuss] FDTD and pade approximation

hi meep users and dear steven. I want to use meep to calculate Q factor and resonance frequency of PhC cavity. I want to use Pade aproximation but I have no information about this? who does have information about this approximation? how can I calculate pade approximation from discerete time series.
