Dopplerjeff,
You are right.
I was thinking that the magnitude of the scattered field should always be smaller or equal to the magnitude of the incident field (because the magnitude of reflection coefficient can not be larger than one). But this is not correct!!!!
In principle the magnitude of...
Hi guys,
I am simulating a single unit cell of a reflectarray antenna using HFSS. I place the unit cell inside an imaginary waveguide (a waveguide with periodic boundary conditions, PEC & PMC) in order to study the behavior of the unit cell. I excite the waveguide with an incident planewave and...
Hello,
Does anyone know the difference between different periodic boundary conditions in HFSS. What is the difference between linked boundary conditions (Master/Slave) and PEC/PMC boundary conditions.
Which one is better to use for simulating the unit cell of the antenna? Master/slave or the...
Hello,
I would like to know the difference between a reflectarray antenna and a tunable high impedance surface(mushroom type structures)!
They both can be used for beam steering.
Thanks,
Ben

Apparently Out of memory means your machine is not able to complete this simulation!!
I am not sure about the first one! why dont you share your .hfss file here so I can take a look!

Thanks,
Here you go! attached is my design!
The more important problem is, how to really see that this structure is able to steer the beam!
Is the RCS idea a good one?! Or there is there any other way?!
Thanks All

Hello all!
I have posted this last night, but I guess I did it in a wrong place!
This time I will also attach my simulation file.
I am trying to see how a patch array (with mounted tuning varactors across the gap between the conductors) is able to steer the beam.(The patches are very small...
Hello all!
I am trying to see how a patch array (with mounted tuning varactors across the gap between the conductors) is able to steer the beam.(The patches are very small comparing to wavelength).
By changing the capacitance between the patches one should be able to reflect the incident beam...
