hi
Iam plannin to do my grad from univ of bremen.Can a foreign student do part time work.If so what are the restrictions and of course the possibilities.
Any details on funding also would be appreciated.
Polarization
hi
The adv of Oly pol ant is that one can reciev inany orientation of the antenna owing to the elec field being along a circle.Also as suggested one can recive orthogonal pols but only at half power.

Dear Atul
This is the best software around for the analysis of reflctr antennas .I have not personally used it but my colleagues have.The analysis and fabricated ones closely match.
Also CHAMP is another software by ticra for analysis of horn antennas
To make life a bit easier....a vector is completely specified if ad only if two parameters of the vector are known....find that and mathematically you are there.Intuitively lets resort to dkace way.....
A vector is just not any other " variable"

hi
Is this message a warning or cant the simln be run.
I have come across such messages but could simulate.thepoint to be noted here is that the aspect ratio is very high..that is you have avery small structure and a larger one.Since the problem is multi mode there would be a lot of...
convolution unit step
a triangular one...to see it intuitively, recognize that the same amount is added/subtracted for any unit time interval...hence the slope shouldbe the same or we get a rising line and then a falling one
is ther a restriction in the value of resisitors.That was one of the fav questions of profs...where in a high gain reqrmnt is given and one is asked to design the amp with restrcn in values of resistors.
The feedback should be lowered by a T divider configuration
Re: EMI
adding to the above points a way to circumvent radn in ckts with traces is to use high dielectric constant substrates.This would result in less radiative interference as the waves are tightly bound to the media.
hi
I would not be able to solve the problem but its a typical mode matching problem.There is a book called field theory of waveguide components, Artech House; authors include bornemann of Univ of Victoria.Certain canonical problems are explained in it.A search on IEEE, on papers by Prof...
Dear faiad
One should know, in what direction the co pol and cross pol of the antenna is.
It would be helpful for one to visualise if the axis of the antenna is algned along the Z axis of the coordinate system.
Now for the procedure.
1)One should first enclose the entire structure or that part...
