Code 8.2: Attenuation Coefficient of Oxygen

Code Name: AttenCoef_Oxygen.m

Description: Code computes the attenuation (absorption) coefficient of oxygen at any frequency 1 < f < 1000 GHz, temperature −100 °C < t < 50 °C, pressure 10−5 mb < P < 1013 mbar, and water vapor density 0 < ρv < 20 g/m3.

Input Variables:

  t:    Temperature (°C)
  P1:    Total barometric pressure (mbar)
  ρv:    Water vapor density (g/m3)
  f:    Frequency (GHz)

Output Products:

  κO2:    Oxygen attenuation coefficient (dB/km)

Book Reference: Section 8-2.3 and Eq. (8.19b).

Code: module8_2.m
