The series resistance of the switch in principle will change the integrator into a PI characteristic (proportional part Rswitch/Rin) - however, for a "good" resistor ratio (small) the influence on the time constant of the **integration** process should be negligible. Don`t forget that also the **finite** and frequency-dependent opamp`s open loop gain distu

Ideal point source (J&M) is challenging in FDTD, its actually a singularity point, at which the signal magnitude is infinity, however, the **integration** over such delta function is a **finite** value. This is very very challenge for differential based solvers. Especially for its near fields, its error is going to be large.

hi every one I am trying calculate stiffness matrix for 2D fem and using quadrilateral element(2 elements). but i am facing problem with the **integration**.
it is giving me warnings with out calculating stiffness matrix. the warning is
Warning: Cannot attach the property of being close to the limit point to limit
variable.
please help me

CST MWS is not suitable for large structure. It is based on **finite** **integration** Technique and uses volume discretization. I think, you should use ADS Momentum of FEKO Software. They are based on the Moment Method. Also, if you are familiar with Ansoft HFSS, so you can use Floque boundary condition to overcome this probl

The TD-FE tecnique is somewhat uncommon. There are some text books that describe it, but I don't know of any codes. In the time domain, **finite**-differences or the **finite** **integration** techniqe are much more popular.

Hi nirmal323,
In the case that one function has **finite** support (-a, a), then the integation in (-∞, ∞) reduces to integrate in (-a, a). But if the function has **finite** support in one domain, it doesn't have **finite** support in the other, so you should integrate in (-∞, ∞) in the other domain in order that Parseval's (...)

Hi,
As far as I can remember any function that has "**finite**" number of discontinuties is integrable.
The idea behind **integration** is to compute the area swept under the function now suppose that the required function has discontinuties at say n points in the range
of **integration** then we can patch these points up as their contribution to (...)

MWS is particularly using the FIT method (**finite** **integration** Technique),
the brother of the FDTD method. Those two techniques are similar but
not identical.

FIT is same as FDTD in cartesian coortinates.
Its interesting as
FIT **finite** **integration** technique
FDTD **finite** Difference time domain
Please upload some tutorial if u have one

The simulation engine of CST is based on **finite** **integration** Technique (FIT), not FDTD. However, FIT used for time-domain simulation has some similarities to FDTD.

Dear all
What is FIT (**finite** **integration** Technic) and it's differanc with FDTD method?
Thanks

I need information about the **finite** **integration** method, basics and methodology. If someone can help me it will be great.
If someone has information about moment method it can be useful too. thanks

I highly doubt that there is a **finite** expression of that integral. It can be expressed by a series if certain **integration** limits are applied.

Do you mean the "limit" in calculus? If so, then the whole modern mathematics is based on it, the differentiation, **integration**, ... All will collapse if there were no "limit". You only got arithmatics or **finite** math.

CST is based on **finite** **integration** Technique. This method is similar to **finite** Difference Time Domain Method; the main difference is that FIT solve maxwall equation in time domain in integral form while FDTD in differencial form. To understand the CST program you can serch for some paper on FDTD method (it is very popular)

i've done a **finite** ground CPW and i drew the **integration** line on one port from the ground to the center line on one side, and one the second port i drew the **integration** line from the other ground to the center line.

This issue was discussed in some other topics.
A few points:
It is called **finite** **integration** Technique (or Method) was invented in 1977 by Thomas Weiland and it can be considered like a generalization of FDTD invented by Yee in 1966.
Yee discretizes the differential form of Maxwell?s curl equations while FIT discretizes the integral form (Farad
