    Notes: [Auszug] IT has been definitely established that the ionosphere responsible for carrying radio waves round the curved surface of the earth is divided into two clearly distinguishable regions1, 2. The lower—the classical Kennelly-Heaviside or the E layer—is situated at a height of about 90 ...

    Notes: [Auszug] IN recent years, a large number of experiments have been carried out on the dielectric constant of ionised air with the object of verifying the Eccles-Larmor theory, which demands that the dielectric constant of an ionised gas should be less than unity. Study of the literature on the subject ...

    Notes: [Auszug] IT is an established fact that wireless signals transmitted from any place are readily received at the diametrically opposite place on the globe. The explanation usually given of the phenomenon is that the ions in the Heaviside layer make the speed of propagation of the waves greater in that ...

    Notes: [Auszug] PROF. COLWELL and Mr. Friend1 state that from results of experiments conducted by them they have been led to believe that, besides the usual E and F regions of the ionosphere, there is a third region—the D region—at a height of 5–55 km. They further say: “Such a layer has been ...
