Hi Guys,
Apologies for the hugely off topic question but as you guys are so into RF (and its been
a little quiet in last few hours ;) I was hoping someone might be able to answer a simple
question, well fairly simple, with caveats no doubt...
As free space has a characteristic impedance of some 376.7 Ohms (or close to)...
Does free space have any (equivalent) 'characteristic' frequency or resonant frequency(s),
no doubt derived from attenuation/gain factors from RF transmissions etc ?
And if so, can the responder hazard a guess as to why, in terms of equations from first principles
or observations from experiment, that such frequency or even such impedance exists and
practical consequences thereof ?
<cough> Thanks ;)
Regards from
Mike Massen
