[Meep-discuss] metamaterials and periodic boundary conditions

2016-07-01 Thread Heligman, Daniel M.
Hi, Is there any way to emulate a large array of split ring resonators by using periodic boundary conditions on one unit cell? Best, Daniel Heligman ___ meep-discuss mailing list meep-discuss@ab-initio.mit.edu http://ab-initio.mit.edu/cgi-bin/mailman

[Meep-discuss] Question about permittivity and permeability

2016-09-16 Thread Heligman, Daniel M.
Hi, I have a simple question. Is the a conversion between SI and meep units for permittivity and permeability or are they the same in meep units? Best, Daniel Heligman ___ meep-discuss mailing list meep-discuss@ab-initio.mit.edu http://ab-initio.mit

[Meep-discuss] trying to find charge density of metamaterials

2016-10-25 Thread Heligman, Daniel M.
Hi, I was wondering if there is a way to find the charge density or near-fields in metamaterials from a simulation. I am trying to find the charge density at the resonant frequency. Best, Daniel Heligman ___ meep-discuss mailing list meep-discuss@a

[Meep-discuss] issue with computational cell size

2016-11-04 Thread Heligman, Daniel M.
Hi all, I have been doing some simulations where I am changing the dimensions of the computational cell between simulations. I have all my simulations I want to run on the same control file and when one simulation is done, I have meep reset itself and and it continues on to the next simulation

[Meep-discuss] Coordinate transformation results don't make sense

2016-11-14 Thread Heligman, Daniel M.
Hi all, I recently tried the coordinate transformation trick to try to fit more grid points in small features of my structures, and the resulting transmission seems to have reflections and pre-pulses that did not appear in the untransformed simulations. I did adjust the courant factor for to a

[Meep-discuss] Issue on computational power

2016-12-01 Thread Heligman, Daniel M.
Hi all, I am currently trying to run my simulations on meep-mpi at a supercomputer. For my simulations I am running them with 20 nodes (12 processors per node) and the simulation takes a total of 30hrs. Since the center running the supercomputer charges you for number of nodes used for however

[Meep-discuss] Over unity reflection

2017-07-21 Thread Heligman, Daniel M.
Hi, I have been recently working on a metamaterial simulation control file it seems to work for transmission but not for reflection. The reflection seems to produce a reflectivity that is over unity. I am not sure what could be causing this issue. Posted below is my control file. Let me know i

Hi All, I am currently trying to simulate split ring resonators on a substrate with a dispersive permittivity. I am having trouble figuring out how to convert the coefficients from a lorentz dispersion model to the coefficients in meep. The equation I am using for the analytical model is depic

[Meep-discuss] in regards to material-dispersion.ctl

2018-01-18 Thread Heligman, Daniel M.
Hi all, Can anyone tell me exactly how to grab the epsilon data from material-dispersion.ctl. The tutorial only tells me to grep the frequencies and epsilon and not much more. And once I have obtained the data, what are the means of analyzing the data. Best, Daniel Heligman
