    Notes: [Auszug] WE were much interested in Mr. T. L. Eckersley's description1 of a method of demonstrating the polarisation of wireless echoes, but surprised to find that some of the results he mentions appear both contradictory to the magneto-ionic theory and also to those obtained when other ...

    Notes: [Auszug] IN a method which has previously been used1 for determining the state of polarisation of downcoming wireless waves, the frequency of a transmitter was varied so as to produce interference maxima and minima at the receiver in the well-known way. By analysing the signal variations ...

    Notes: [Auszug] Radio Exploration of the Ionosphere IN the usual method of ionospheric sounding, short trains of radio waves are sent vertically upwards and received at the ground after reflexion in the ionosphere. From the measured time of travel the equivalent height (h1), at which the waves would have been ...

    Notes: [Auszug] THE correspondence in NATURE of Feb. 8 (p. 198) on the subject of the wave-band theory of wireless transmission has directed attention to the question of the physical existence of the so-called ‘side-bands’. The following experimental results seem to indicate that these ‘side-bands’ have, in ...

    Notes: [Auszug] WE are interested in the measurements which Khastgir, Chandhuri and Sen Gupta described in a recent letter to NATURE1, apparently confirming the occurrence of ‘negative attenuation’ of wireless waves first noticed by Ratcliffe and Barnett2. Some years ago, we ...

    Notes: [Auszug] OUR knowledge of astronomical bodies is almost entirely derived from observations of the electromagnetic waves which they emit. The earth's atmosphere forms a very complete absorbing blanket for most of these radiations ; but there are two 'windows' in the atmosphere, one in the region of optical ...
