Hey, a plane wave is an approximation that is designed to simplify mathematics. A true plane wave cannot physically exist at any frequency. However, if we sample a 15kHz wave from distance 2D^2/lambda with a small loop antenna, then it will look like a plane wave to us, due to the antenna aperture being much smaller than the wavefront. Hope it makes sense?
Hey Hwansu, These are the probes featured in the video: www.com-power.com/products/near-field-probes/ps-400 I don't think I ever really had an emissions problem anywhere near 5ghz, but they're definitely picking up wifi and lte in the building!

Good presentation! Just joined your channel. Thx for sharing. 👍👍
Thank you!
Can we produce plane wave of 15 to 30 khz

Which near-field probes did you use? Did you find them effective for high frequencies, particularly close to 5 GHz as well?

Hi Dr. May I have your fb?
Hey, I'm not using FB. But if you add me on LikedIn, I will be happy to asnwer any question.
Thanks!
