hi, i'm trying to simulate a wave using fdtd based on a reference paper. the source is modulate gaussian source with the equation below:
Ei(t) = e-(t-t0)2/tw2)sin(2*pi*fmt)
where t0 is time delay, tw is gaussian pulse width, fm is frequency of sinusoidal component.
the paper shows an example...
Hi,
i am simulating using FDTD.
my computational domain is 1D with a dielectric medium at the center. i have a Gaussian input that moves from left to right of the medium. i put a probe both at the left and right of the medium and saved the fields at these locations at every time step.
does...
mesh of revolution + matlab + data
hi. the data i gave is axially symmetric so want to rotate it around the axis. the result i need should be something like the figure below.
cartesian mesh code in matlab
tnx.
the data i have is only 1Dimension. i am supposed to rotate the data about r=0 so that i will have basically a 3d data(body of revolution) and then plot it. but i don't know how to do it in matlab. i hope someone could help me.=)
matlab beam profile
hi. i have a data of a beam profile that i simulated. i plotted it in matlab using the normal plot and i got the plot below.
now i want to plot it in 3d such that i would have a 3d profile of the beam but i don't know how i'll do it in matlab. pls help me. i need it...
hi!
problem: i want to plot a full 2d cross-section of a gaussian beam using pcolor. i only have a 1dimensional data which is from the axis to a maximum radius.
Re: cylinder FDTD code
hi fatma.. i'm trying to simulate a fiber... i'm using tf/sf and Mur's ABC at the moment... now i want to simulate a fiber about 1m... the problem is the problem is too big :D... can you tell me a hint on how to solve this?:D
treating late time instability
hi can i have the paper?=p i need it coz i'm trying to simulate a long structure
my e-mail address is brrrrrgrrrrr@yahoo.com (5r's^_^)
hi... i have a question regarding the use of PML. what are the maximum conductivities that you use in your PML,(both for electric and magnetic)? i ask this because i am having a problem when i implement the condition sigma_magnetic/mu=sigma_electric/epsilon. my update coefficient for the...
