1) from http://ab-initio.mit.edu/wiki/index.php/Meep_Reference#source the width allows one to turn on the continuous-src smoothly so you don't introduce high frequencies 2) from http://ab-initio.mit.edu/wiki/index.php/Meep_Reference#Field_computations this computes the integral of the electric field energy (E*.D/2) which is quite different than the poynting vector, E*xH. if the 'box' is not a volume but a line or a plane then a lower dimensional integral is used. there is no 'dir'. 'field' is a meep global data structure which stores all the fields. it get sets once you initialize the simulation either with a run or add-flux region. you don't need to touch it directly. gp ------ On Aug 18, 2006, at 12:00 AM, hbchen8888 wrote: Hello every one: |
