good post.
also voltage/current not unique defined for quasi-TEM. V depends in integral path.
this issue was discussed in agilent hfss manual but not in ansoft. they were from the same source and now unified again, any way
weird, ansoft has such a good code but lousy manual
maybe save some...
mike has a FGCPW. not sure it is a common practice that a metal package (side wall) would be close (or contact) to cpw grounds in this case.
for FGCPW, the two close sode walls could cause resonance? affect impedance? in short, more packging effect??
not sure, please advise.
-yes. you are...
thermal related rf mems papers
midnite posted this on "EM simulator". i guess he wants to know RF mems switches, besides some points of course, like myself.
rf mems switch is pretty stupid and straightforward for EM simulations
you use good conductor (Au, Cu, Al) and nice dieletric (good Si...
reverse scenario:
you have very narrow ground conductor... gorund width is comparable to center strip width. it is called finite-ground CPW (FGCPW)
port width> 3(2g+w) does NOT apply at all. you can forget the crit#1.
make the enclosure surface big enough to cover the whole line with some...
add another criteria:
- this is engineering, sometimes, art, but 99% time/composition are definitely not science
- but this 1% science only determines how we use screw driver. so it becomes intuition eventually
here is my answer
1/ should be satisfied most of time.
2/ should not be a problem...
