I heard that two simulation tools operate similary.
But, when I simulate the nano aperture in optical region,
these two results has different resonant frequency.
FDTD : 970nm
CST MWS : 1250nm
both of cases, I use the grid size of about 2~2.5nm (I think it is enough)
and same structure...
Hello. I have a question.
I am using now CST MWS 2009 Frequency domain solver program.
At 633nm (optical wavelength),
I want to use the gold metal aperture in this wavelength region.
So, I have to make the new one using the normal material setting.
In normal dielctric material with...
In CST, MWS, frequency solver,
I excite the x-polarized plane wave of 1v/m at the end of the z_min.
Every volume is filled with air then there is no problem. Every field intensity
in every point is about 1v/m.
but,
when every volume is filled with dielectric material(not vaccum),
every...
I simulate the structure of gold nano aperture at specific frequency
(frequency of 474THz, wavelength of 633nm)
When I simulate this structure, I use epsilon value of -9.514 and tangent
delta electric of 0.128.
(In other words, epsilon = -9.514-i*1.218)
There is no problem when I simulate...
I simulate the structure of bow-tie nano-aperture with CST Microwave studio 2008.
(there is a metal slit and we excite the plane wave foward to the metal slit and measure the power transmission at the opposite side of metal slit)
In frequency domain solver, there is a adaptive mesh refinement...
software: cst2008 SP5, MWS, frequency domain solver
1. mesh size : 2,000,000 (no adaptive mesh refinement, 1st order solver)
2. mesh size : 400,000 (6 adaptive mesh refinement , 2nd order solver)
Two results are very very different (about 1000 times!!!!!)
plz help me;; which result should...
In CST MICROWAVE STUDIO frequency domain solver,
1. mesh 2,000,000 & 1st order(low memory)
2. mesh 350,000 & 2nd order(high memory) & adaptive mesh refinement(about 5~6 number of passes)
In general, which is more accurate?
I use CST MICROWAVE STUDIO 2008....
(sorry .. my english is poor)
There is a aperture of nano-size on the surface of the metal(gold) and we
emission the plane wave foward to the aperture and observe the Power flow distribution.
(frequency : 309Thz , wavelength : 970nm )
This is what I...
