[Meep-discuss] reading epsilon from file gets different resuls

2014-04-30 Thread Ehsan Saei
Dear Steven and MEEP users, I try to simulate a complicated structure using MEEP. Rendering the structure takes a long time so I would rather to create epsilon one time and use it for the rest of my simulations. I tried to use epsilon-input-file function of MEEP, but I saw that the result of

[Meep-discuss] why the energy spectrum radiated by a point source doesn't match with the spectrum of source itself?

2014-04-22 Thread Ehsan Saei
Dear Steven and MEEP users, I simulated a point source which is located in free-space (air ) and tried to compute the power radiated by the source and travels through a cubic that surrounds the source. After plotting the data I have noticed that the power has a frequency center different from

[Meep-discuss] nested loop

2014-03-26 Thread Ehsan Saei
Dear MEEP users, I wanted to define a structure using nested loops (map function). Here is the code : * (define structure (map(lambda (i) (map (lambda(j) (make sphere (center i j (+ i j) ) (radius r) (material dielectric) ) )(arith-sequence 0 dx 10) ) )

[Meep-discuss] Some questions about LDOS calculation

2014-02-16 Thread Ehsan Saei
Dear Steven and MEEP users, I have read the LDOS tutorial on page: http://ab-initio.mit.edu/wiki/index.php/Meep_Tutorial/Local_density_of_states . I have some questions about details of LDOS calculation. As it is mentioned in the page:LDOS is equal to: So we need to run a point source at
