Well, I'll let you know more as I learn it, biff44.
I did the same thing with electric TLINEs, btw.
We're trying to use time delay for filter tuning, a la Agilent AN 1287-8.
take care...
Dear amirke,
The safe thing to do, since Avago doesn't have any *.snp files online for these things, is to contact Avago directly.
Go here:
If FBAR is linear and passive, then Sxy = Syx. IIRC, this is true, but you should go ahead and inquire.
Hello, kput,
Presumably, you are referencing Koolen, et al from 1991. I cannot access it on my APS account, but probably wouldn't read it carefully enough anyway.
There's plenty of stuff on de-embedding on the internet, but it might be best to start first with your fixture. What can you say...
(Yeah, I know; I'm responding to my own dead thread. I don't think it means I'm crazy, though.)
Just in case anybody searches up this poor little orphaned thread, the answer to Q1 is, "Yep, evidently." I took a look at Matlab's online help documentation, and found plenty of similar syntax. So...
Sorry, ccwjames, I've been travelling.
I am "pretty sure" that what you are simulating is not an error, at least the Er part. If you filled your capsule with a high Er material, similar to tissue in character, wouldn't you expect the frequency come back down?
Perhaps it might be a good idea...
...erm, except you just described the change I asked you about. The antenna is immersed in a low Er medium (your capsule) which is in turn immersed in tissue.
Yes, it is completely normal that the frequency would go up when the Er surrounding the metal parts is reduced.
Re: Difference between "radio frequency alternating current" and " radio waves "
The answer you seek is contained within Poynting's Theorem.
Some of us find several serial question marks annoying, fyi.
Howdy,
I am learning about transforming frequency domain (S-parameter) data to time domain data using IFFT() in Genesys 2012.
I didn't know this back then, but there has evidently been something called "Math Language" incorporated in Genesys since 2008. The Help file for 2012 says,
Question...
INGALLS: What you have shown is not a patch, but a meandered 'thin wire' antenna (I believe). It also appears to be loaded so as to have more than one band of operation. As to how the signal propagates, that is a very complicated question that depends not only on the meandered trace itself, but...
For that, you will need something like this: **broken link removed**
Is this a research project? I only know of such antennas as being implemented by the medical equipment vendors; each application is custom made (in my experience), so there is not likely to be anything available commercially...
Maybe a little bit (the length more than the width, assuming linear polarization) because it is so hard to keep their mutual impedance at 'zero'. Their input impedances will also change, if only a bit.
Also, the array spacing might need to be adjusted from calculated values to get the thing to...
