This volume presents an up-to-date survey of the theory and practice of radio wave propagation involving transmission through and reflection from the ionosphere. A brief historical introduction is followed by such topics as radio techniques, plasma theory, oblique transmission, earth-space, amplitude, ionospheric disturbances, ELF, VLF and LF, medium waves, HF and VHF. The work will benefit radio engineers whose systems are affected by the ionosphere, researchers and graduate students studying ionospheric physics and communications.
