product is testedfor radiated emissions compliance at 150 MHz where the distance between the DUT and the measurement antenna is 16 ft. The measurement antenna provides 0.2 V for every V/m in the incident field and is connected to the spectrum analyzer by 20 ft of coaxial cable (attenuation = 6.2 dB/100 ft at 150 MHz). The voltage measured by the spectrum analyzer is 36 dBμV. Determine the antenna factor in dB.

Asheet of steel 1.5 mm thick has nitrogen atmospheres on both sides at 1200oc and is permitted to achieve a steady-state diffusion condition. the diffusion coefficient for nitrogen in steel at this temperature is 6 x 10- 11 m2 /s, and the diffusion flux is found to be 1.2 x 10-7 kg/m2 -s. also, it is known that the concentration of nitrogen in the steel at the high-pressure surface is 4 kg/m3 . how far into the sheet from this high-pressure side will the concentration be 2.0 kg/m3 ? assume a linear concentration profile.
