    How to managing one NUMA (Non Uniform Memory Access) machine ?

    Hi, We have one 4CPUs server with AMD Opteron 61xx (2x6 cores). But this is a NUMA (Non Uniform Memory Access) machine. What is the best way, then OS ?, to optimize the management of this kind of machine ? I can read somethings Windows Server 2012 on the WEB... BR Chris

    how to understand field distribution in CST

    Hi, You need to create one or more monitor E-field (by solve menu), and you can choose frequency in this. After the simulation, you will find the 3D results : adjust the view parameters to visualize properly the fields (you can extract severals 2D plane of). BR

    I am looking for users of CST MicroWave Studio

    Hi, Nobody use CST MicroWave Studio ? Just, you could communicate to me your configuration : CPU, RAM and CST version. Waiting for your answers... Best regards.

    CST MWS re-simulation with higher accuracy

    For antenna, generally, the best is the Transient Solver. If your antenna structure, has a very hight resonance and has to little number of meshcells, you could use to F-solver. BR

    Beam steering using single antenna

    Hi, Yes. It is not easy to control the pattern without array principle antenna ! The last solution is to defocus the dipole-feed behind one reflector like one parabola... but I am not sure that is the best solution. I don't know sufficiently your specifications to help you correctly. Regards

    CST MWS re-simulation with higher accuracy

    Hi, It depends of your structure, is it resonant, is it an antenna... generaly, if you decrease the accuracy value, you must be carefull of your frequency range : you will have to decrease it. About the simulation time (in help CST MWS) : BR

    900MHz RFID Dipole antenna impedance measurement issue

    OK rf1008. Now, could you describe your backround and boundary conditions of simulation HFFS ? How do you made your exitation ? with coaxial ports shielded or not... I think that you need to check the independance of your antenna. BR

    Beam steering using single antenna

    Hi, Just a question : Can you use a reflector with your dipole, like a small parabola or corner-reflector ? BR

    900MHz RFID Dipole antenna impedance measurement issue

    Hi, I fear a problem similar to quantum mechanic ; it is not a joke ! The system under test (your RFID antenna) is disturbed by the the measurement system... I believe. This test seems very difficult to give a good measurement. Could you simulate your RFID antenna with 3D-EM software ? Maybe...

    [reflectarray antenna]---> cross polarization simulation using HFSS or CST

    Re: [reflectarray antenna]---> cross polarization simulation using HFSS or CST Hi, 1) Create (in solve menu) Farfield Monitor(s) @ n frequency 2) Simulation 3) The results will are in the farfield directory -> choose the good representation (ludwig 3 linear or circular) by click right ...
