Hey guys, I’m a high schooler designing an experiment to test polarity modulation for em waves. Before I study complex methods of polarity modulation that involve the use of crystals I want to use a simple laser and rotating a polarizer while the laser differs in its intensity for brief...

DaveE; I do research the concepts you guys mention and I mention. Perhaps not to the extent you guys know it but to some extent nonetheless. I made the mistake previously of studying too much AM theory rather than practicality which is why I want to set up this experiment (which the details are...

Whoops, my apologies I fixed that lol

DaveE; I would use the photo multiplier before the polarizer. Also will that thin film polarizer and fiber topic work?

Dale; oh alright, I suppose I could do that as a start as the parts needed for what you’re proposing is just as a film polarizer and my radio which are some parts I’m gonna use for my experiment anyway. Perhaps I should add a way of observing to ensure the radio signal is polarized. Also...

DaveE; I don’t have a laser as of now but I plan to buy one soon for this. I completely agree this is a complex field, I for one, don’t know much in the grand scheme of physics let alone specific niche fields such as optics. I reviewed the three optic phenomenons you linked, and to be quite...

Dale; I mean I guess that polarizes rf signals but what does it accomplish? Cause I want to begin experimenting with polarity modulation but just polarizing rf signals doesn’t mean I’m modulating any signals. I feel like what I proposed, as long as it’s not completely wrong which from what I’m...

renormalize; unfortunately I don’t have access to the whole research article to read their work so I could only read the abstract. However, I do agree with you that the use of metasurfaces is likely more efficient than my mechanical method. Perhaps I might involve metasurfaces in a second...

Fred; well yea I could do that, I did some research in that, here’s a link of a video I found about it: Link. However that’s not my goal of this experiment, my goal is to test my proposed type of modulation (polarity modulation). It is quite weird but I want to ensure it’s not wrong. Dale...

That is what I am trying to accomplish.

Dale, Is the concept good?

Dale; so I’ve been taking a while(basically the whole day) to respond as I’ve been reviewing the resources you’ve provided and going back to the drawing board as you had suggested. I know the existence of pulse code modulation however the medium of optical fiber I didn’t know. I’ve thought of a...

Renormalize; an electromagnetic wave is being polarized. As for the garage door, I just thought of a quick example of what I propose, your right they probably use LED light beams. I haven’t thought enough or did enough research to consider whether I want to use laser technology or simply radio...

Dale; well obviously I know it’s not an effective method as simple vector addition tells you this isn’t valid, however, I got some results (not much though). Furthermore, I don’t know of any other method that follows the conditions I mentioned above of aligning the magnetic fields so...

Dale; well, I’ve gotten some results from my experiment, just not much to make it anywhere near effective. However as previous said, I don’t know of any way to bypass the issue stated above of the external magnetic field inducing a emf on the first magnetic field if it were aligned with the...
