The standard experimental method is to vary the attenuation length, keeping the aperture plane at the fixed source-to-FAC distance, and thus to derive the effective attenuation coefficient for the air kerma.
Davis used the UW Attix free-air chamber [34], with an attenuation length, L, of 19 cm.
The basic difference in the coupling mechanism between a conventional coupled-line backward coupler and a CRLH coupled-line backward coupler is that, in the former case, coupling is related to electrical length [beta]d, whereas in the latter case, it is related to the attenuation length [alpha]d.
