Here is the input data file format Build V1.0.1 Date: 5/20/12 By: Michael Liu liu.zecheng@h.mbox.nagoya-u.ac.jp 1-757-4231507 PML2DTM v1.01 PML2DTE v1.01 are compiled and run on Solaris, copy and run. tar -xvf *.tar to extract all files in tar Note: 1. follow format strictly, else the data will not be read correctly and program will not run correctly 2. Verification is written in echo2dtd.prb 3. Lower/upper case matters 4. no blank lines between data 5. no comments allowed between data !**sampletstep, integer, the time interval for writing into GIF file !**negative means no writing** -1 !**nb,nu,R0, !**nb: integer, number of PML layers** !**nu: double, the order of PML function !**R0: double, the normal reflection coefficient, affect a lot 10 2.0 1.0E-10 !**nx,dx,ny,dy*** !**nx,ny: integer, number of cells along x and y direction !**dx,dy: double, size of cell along x and y direction 101 0.01 101 0.01 !**dt,nt** !**dt: double, the time step, should follow stability check !**nt: integer, number of time steps to be calculated 1.6667E-11 400 !**x1,y1,x2,y2,srcshape,wave,amp,freq,t0,tw,srctype,tsrcstop** !**to describe the source !**x1,y1,x2,y2: integer, the 2 points of a rectangle. !**x1,y1: the coordinate of the lower-left point !**x2,y2: the coordinate of the upper-right point !**srcshape: how the source is distributed in the rectangle, !** UN: uniform !**wave: only support these 3 sine: a sine wave gauss_lp: gauss pulse gauss_bp: gauss pulse modulated with a sine wave !**amp: double, amplitude !**freq: double, frequency !**t0: time delay, any for sine,should put 0 !**tw: pulse width, any for sine,should put 0 !**srctype: only have 2 value: hard: hard source soft: treat as a soft transparent source !**tsrcstop: double, when to stop the source, (in unit of tw) !** 0: will not stop during simulation gauss_bp 1000.0 477460000.0 1.3333E-9 5.0E-10 soft !**numofmats: integer, number of materials** 3 !**mater,epsr,mur** !**mater: material number, 100 is for source, 200 is for PEC !**epsr: double, epsr !**mur: double, mur 1 1.0 1.0 100 1.0 1.0 200 1.0 1.0 !**numofregions: number of regions** 1 !**mater,shape,x1,y1,x2,y1,patchtype,radius** !**mater: material number, refer above !**shape: the shape of this region R: rectangle D: disk, including circle and ellipse !**x1,y1,x2,y2, define the rectangle region !**patchtype: the sub-type in the rectangle region NA: rectangle LL: low-left triangle UL: upper-left triangle LR: lower right triangle UR: upper-right triangle !**radius: only used for disk, I am now considering to remove it 1 R 1 1 101 101 NA 0.0E+0 !**number of source rect 1 !**srcpatch, x1,y1,x2,y2,patchtype** R 51 51 51 51 UN !**PCsupport: only 2 valuse support: PC:YES and PC:NO** PC:NO !**if photonic crystal is present, ie.
