Effect of static Magnetic field on EM in near field - RF Cafe Forums

RF Cafe Forums closed its virtual doors in late 2012 mainly due to other social media platforms dominating public commenting venues. RF Cafe Forums began sometime around August of 2003 and was quite well-attended for many years. By 2012, Facebook and Twitter were overwhelmingly dominating online personal interaction, and RF Cafe Forums activity dropped off precipitously. Regardless, there are still lots of great posts in the archive that ware worth looking at. Below are the old forum threads, including responses to the original posts.

Hi All

I want to know how

A Fixed magnet (which casues its own static magnetic field) will affect any other Electromagnetic (radio) signal especially when we are trying to carry energy/information using magnetic component of EM wave which is typical for near field applictions.

Best Regards

As long as we are concerned only by the antennas, I don't think a DC field will have any impact. Antenna are resonnant circuit, and so are also the receiving networks, a DC field will be mostly rejected.

Would the situation you describe be a problem we would have a serious issue with the earth magnetic field.
