    [400pts] can you solve this problem?

    Hi..maryam_2 I had all the solution of this book(time harmonic electromagnetic fields)..how can i help you?

    Looking for models and information about SAR

    a question for SAR?? Hi..r.balh i am working in specific absorption rate of antenna design, can you help me for the setup in HFSSv10? Thx

    CPW lumped port define

    Hi, The defined of lumped port is easily to me. But I don't understand your question, maybe you can take a picture about feeding point, that's availed us. Best regard

    band-reject question?

    Hi all! I'm want to ask a question about band-reject design? If i used a slit to generate a band-reject characteristic on antenna design, why is the length of slit usually design at quarter-wavelength of rejection frequency? What's the phenomenon means?

    About pattern and gain of antenna

    hi llololl!! The uwb application spetrum is from 3.1 to 10.6GHz. At your simulated results of antenna gains, I could assumed in the higher band(7-10.6GHz) has no resonate mode exist. You can adds a short current path to generate a mode. Therefore, a wideband operating can be obtained.

    How to calculate the co & cross polarization in HFSS?

    cPoL&XPoL? Hi vaakaa, There is the radiation patterns steps in HFSS... 1. insert far field setup > Infinite sphere.. and set phi and theta. 2. results > report type : far field, display type : radiation patterns 3. in sweep part: select "sweep design and project variale values, Description of...

    SMA input port for CPW monopole antenna in HFSS

    hfss monopole antenna edaboard cpw hi kwokhinglai!! The design of the file "LumpPort for CPW.rar" has a badly mistake, that is the "air objects" is no boundary exist. You have to set the air becoming assign boundary > Raidation. And, run it. That will be ok.
