RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

The Black Oak Group Measures Real
Relative Permittivity and Conductivity of Air

The Black Oak Group logo

Framingham, Mass. / 11-SEP-2015

The Black Oak Group has measured the broadband complex permittivity of air. Maximum excursions over 50 MHz to 500 MHz for the real relative permittivity were +0.016 and -0.016 compared to one (1) and for the conductivity +0.0 and -0.00064 Siemens per meter compared to zero (0). The measurement set-up is particularly well suited for commonly encountered low-loss bulk complex permittivities found in dry wood products for the lumber industry, dry grains and cereals for agriculture and the food industry, sifted homogeneous soils for agriculture and machinable homogeneous dielectric samples around 3 x 3 x 3 inches in size.
