Hi,
I'm looking to determine the dangerosity of an equipment inside the
Rayleigh zone: In this zone, it's assumed that the full energy of the
radio equipment is transmitted without any attenuation, after this
zone, the Fresnel zone appllies with attenuation on a free space.
The rayleigh zone is within < dē/(2*lambda) but I could not determine
what is d ? Is someone can help me ?
Thanks in advance |
