Nicholls and Schelling (‘Nature’, March 7th, 1925).1932E. V. Appleton in Jrnl. Inst. Electr. Engin. LXXI. 645/2 It is highly probable that interference between the various magneto-ionic components of singly- and multiply-reflected downcoming waves is partly responsible for resultant intensity fading.1973Physics Bull.
