Do I really belong here?
Greetings iMechanicans
I've been struggling with a optics project for almost 3 years. I say struggle because my lack of a formal physics education leaves an accurate hypothesis out of my reach. I understand solid-state physics, as well as electromagnetic wave theory from my 40+ years of experience and research in these fields.
I hope to spark the mind(s) of anyone who could possibly explain an optomagnetic anomaly that results from this simple Superparamagnetic event that I've created.
Should I leave and try to find the answer elsewhere?
or is anybody game?

Re: Optics (or superparamagnetic event)
Hello Timm,
I am ears.
Speaking personally, I will certainly *read* what you have to say. I may even write back to you. Of course, I cannot be sure if I would have understood what you write before writing back. :)
But, seriously speaking, a lot of people here come from amazingly different backgrounds and carry quite a wide spectrum of interests. (For instance, note the topic of the current month's journal club.) May be someone will be able to help, or at least provide you with suitable pointers/directions--that is, just in case you "really don't belong here."
superparamagnetic event
Hello Ajit
The phenomenon I wish to discuss is both optical and mechanical.
If you are familar with the etalon, you know it's the basis for the Fabry-Perot interferometer. The distance between it's plates determine what resonant frequency will pass through.
I've built (and patented) a new type of lens that utilizes a magnetorheological fluid composed of nano-magnetite particles (~10nm) suspended in an oil-based colloidal. It's construction is similar to the etalon, but instead of an air gap, I use the fluid, sealed in a vacuum between two sheets of optic glass (flat to less than 1/2 wave accuracy).
The test setup:
a] Red 25mW laser.
b] the superparamagnetic lens.
c] viewer (eyes) or camera.
d] a white screen.
1. Laser beam passes through lens and on to white screen.
2. Without a magnet next to the lens, there is only a red dot on the screen.
3. Placing a 1 Tesla magnet next to the lens but out of the path of the laser beam results in a 180 degree deflection of the beam, in a direction proportional to the polarization of the magnet's field.
If I use a hemispherical screen, the 180 degree deflection is clearly seen.
Faraday rotation is not capable of such a large angle of deflection, and I've ruled it out.
The particles do align with the field, but how is it possible to deflect a beam to such a great extent without a prism or beamsplitter?
I have many photos of this event, and can provide links, if you desire.
Thanks for your interest and support.
many look but few see...
