I am building up a new workstation to do heavy duty electronic analysis calculations. I would also like it to work well with Solidworks.
I notice that Solidworks has a list of "supported" graphics cards. Prominant in the list are the Nvidia Quadro cards.
Not being a computer geek, I am...
Anyone here familiar witht he San Onofre plant? Just saw their mock drill going on on tv. The announcer mentioned that the plant was near or right on a fault line? Also, the brief picture of the plant showed it to be nearly at sea level with a very short wall to stop waves from flooding it...
Whenever I use the scroll knob on my mouse, mathcad goes absolutely nuts! It scrolls up and down forever, and refuses to stop until I do a ctl-alt-del and end it. It is a microsoft mouse.
It is irritating since I use the scroll know all the time, and I just intuitively use it every once in a...
If I had limited package size, and wanted two antennas for some spatial antenna diversity, which option would be better: Option A or B?
I assumed Option A, but then I realized I was not sure.

End of the quarter sale going on at solidworks. I have been evaluating solidworks recently. I like the format, and it seems to be gaining traction with some of my clients. However, one big downer with Solidworks is that the files are not backward compatible. In other words, if I have...
Dear Colleagues,
PLEASE forward to interested students.
The IEEE Microwave Theory and Techniques Society (MTT-S) UNDERGRADAUTE/PRE-GRADUATE scholarship application DEADLINE has been EXTENDED to JUNE 15!
The purpose of the scholarship program is to attract undergraduates to the microwave...
I am using the student version 2009 sp3.0 to learn and evaluate solidworks. Someone just sent me a file apparently done in 2010 solidworks, and my version can not open it. Doing some google searches, I see some old posts (2004) saying there is no way to save files from one year's version into...
I have a 2 X 2 beamforming mimo 2.4 GHz WLAN card. I want to come up with a repeatable performance test in an enclosed space. The antennas are shortened monopoles, 1" long. They are spaced around 10" apart. I know from theory that if I placed a test antenna some distance L away from the...
I have Mathcad 13, on Windows XP Pro SP3. Every once in a while is just stops working. I have found that to fix it, I have to go into control panel--administrative tools--services and re-enable the service C-dillaDDA11BA. Apparently various malware detection programs or microsoft updates can...
I have a pretty large cavity (microwave heating experiment) that I am doing experiments in. It has to hold a high pressure (200 psi), so initially it was design out of steel. But now I find that the energy is not being absorbed so much in the load as I expected, but it is also being...
How many threads have to catch in a 1/4-20 bolt to get the full rated bolt strength? I can not find it anywhere. I vaguely remember that 4 threads is all you need. right/wrong?

Anyone have proven dimensions for a 24.15 GHz patch antenna? Linear polarization. If so, let me know dimensions and material details. Need to make a quick prototype.
Thanks,

If you had to make a waveguide pressure window at 2.45 GHz, narrowband, 30 KW CW, 100 PSIG pressure, and 700 deg F temperature on one side, other than rolling on the floor laughing, how would you recommend getting started? What window material, how would you bond it to the flange, what flange...
I have a large steel pressure vessel at 100 PSIG with gases inside. Gas temeprature might be as high as 600 degrees F.
I need to pass a long ceramic rod, perhaps 1/2 inch diameter, through the side wall of the vessel. I am looking for a bearing that can hold the rod at the vessel wall, allow...
Anyone out there have approximate dimensions for a WR-1150 or WR-1000 waveguide to coax adapter? My empirical attempts have been coming out with pretty poor VSWRs!

Q1: How does one go about one-handed testing using a standard voltmeter to see if a 240VAC 3 phase circuit is de-energized?
In single phase, I could just hook an aligator clip to neutral or earth ground, and use a voltage probe to see if any of the wires are hot.
But in 3 phase, can I do...
Anyone have any standard antenna or leaky waveguide designs they can share for microwave heating applications at either 915 or 2450 MHz? Am looking for designs that can uniformly distribute heating energy over the inside of a length (tbd) of 2 foot or bigger diameter pipe. Thanks!

If I wanted to build a collinear receive antenna, similar to the one in this link:
http://www.rason.org/Projects/collant/collant.htm
But did not want it to be 7 feet long...
could I use dielectrically loaded quarterwave sections, maybe with er=9.9 loaded plastic dielectric, to shorten the...
I have finally gotten around to publishing a website online. One project I want to do is to provide useful microwave design information (oscillators, transmitters, receivers, filters, antennas, wireless systems, etc) to share with the engineering community. I have started a LINKS page, and...
Does anyone know, for certain, if there are unlicensed ISM bands available in Israel? For instance, is there a 433.05-434.79 MHz and 920-928 MHz band, and what are the requirements for each? I am getting all sorts of conflicting information.
