    what do GDP/ZDP/ PYP mean in DSP datasheet?

    hi guys, please tell me the package abbreviations of GDP/ZDP/ PYP means that usually seen in dsp datasheet. 3.3-V I/Os, 1.2‡-V Internal (GDP/ZDP/ PYP) 3.3-V I/Os, 1.4-V Internal (GDP/ZDP) [300MHz] THX!

    Why the gain is a little larger than directivity in HFSS?

    the gain is a little larger than directivity in HFSS, even for simple dipole. How can this happens? can anyone give me some hints? thanks!

    Circular waveguide...Model Attached...Plz Help

    The kecbackbencher's result is right. I have not got your ideal, the polarization of E makes no differences for circular waveguide.

    Polarizing the E-Fields with HFSS

    It is said that Polarizing the E-Fields is needed for square or circular ports and the HFSS aligns the field with the defined integration line if you select Polarize E Field. Why two modes are needed for setting the E-Fields Polarizing?

    dispersion PML implementation in FDTD

    pml implementation fdtd In FDTD arithmetic, the PML layer is related to neighboring dielectric. if the dielectric is dispersional and are tightly touched with the PML layers, how to handle the pml layers, can anyone tell me about this or provide some materials about this?
