    8051+Eprom(2764) simulation problem

    it's useful. Thank you!

    Ansoft 3d via design "Via Wizard 3.1" needed

    it is free ,anybody can download it .

    Via Wizard 3.0 in HFSS? I cannot generate the project

    HFSS version must be 12 or above.

    coupling matrix by optimization

    you could reference S.Amari's paper on this topic. there many ways to handle this problem.

    Coupling Coefficient Calculation

    Its transmission function is Chebyshev . first compute g value . then compute normalized coupling coefficient .last renomalize. the formula is easily found in book. or u could synthesis in Cameron's method.

    Coupling Coefficient Calculation

    In the classic books ,like matthai's book , there is formulas.actually , any book involved in filter design has the formulas you want.

    Import and use touchstone files within HFSS

    it is difficult in HFSS. you could export your HFSS design results to Designer , with your capacitor s2p filter, simulating.

    HFSS use of Datatsets - need to define a goal function

    HFSS use of Datatsets are them have the same array size ?

    Very bad results of HFSS for an X-band Waveguide Filter

    results in hfss as burton said , the coupling part is very important and lmain for the load effect .you could use dummy project to improve the dense of this part.

    mode in a cylindrical waveguide

    perhaps , you could compute several cutoff frequencies with different modes , and compare them with your operating freqency . Kc of TE10 determine the propagating mode . That is The dimention decide the Kc of TE10. as for the distribution of E or H , the simple method is through simulation tools...

    Very bad results of HFSS for an X-band Waveguide Filter

    mesh seeding,hfss you should mesh more densely to get an accurate results. HFSS is good for this waveguide structure.

    Cavity resonator questions??

    maybe your modal has some problems . you can upload the files , someone could help you .

    Coaxial Waveguide Cutoff Frequencies

    Coaxial Waveguide propogate TEM mode . so it cutoff frequency is infinity.

    Extracting Data to Computer from Agilent 8703A VNA

    you could go to agilent website to see if there is some software to use . i ever used one.

    The relation between the coupling cofficient and coupling bandwidth

    Re: couling bandwidth coupling bandwidth is the value that normalized coupling coe multiples bandwidth. it divide f0 equal to coe.
