Kudinov* Siberian Federal University 79 Svobodny, Krasnoyarsk, 660041, Russia Received 12.12.2014, received in revised form 18.01.2015, accepted 26.02.2015 The article describes the potentiality of submarine reception of radio signals emitted by shore radio transmitter with a horizontal antenna in the wavelength range based on interaction radio and acoustic waves in skin-layer. <...> Свободный, 79 В статье рассматривается взаимодействие электромагнитных и акустических волн в ионопроводящих средах, в частности, в морской воде для решения прикладной задачи обеспечения радиоприема подводными аппаратами на больших глубинах. <...> The need for the reception of radio signals under water without surfacing of underwater vehicle (UV) emerges in many problems of both military and civilian technology, in particular for navigation and control of the UV including the under-ice diving, during the seismic sensing of the earth in the Polar Regions, when the sea surface is tightly covered with pack ice. <...> Consider the problem of signal reception under the sea surface making use of the effect of signal heterodyning in the skin layer of the electromagnetic wave by «highlighting» the water by ultrasound from the board of an underwater vehicle (Fig. 1). © Siberian Federal University. <...> All rights reserved * Corresponding author E-mail address: ekanikolenko@yandex.ru # 350 # Georgy Ya. <...> Using of Electromagnetic and Acoustic Interaction for Submarine… In the fi gure, the electromagnetic wave (EW) emitted by coastal or aeronautical radio station carrying the message signal becomes elliptically polarized at the border water-air with a vertical component of the electric fi eld E1z and H1y and horizontal components of the electric and magnetic fi elds E1x respectively. <...> At the same time the water surface is irradiated with directional acoustic radiation 3, formed by means of ultrasonic emitters located on the hull of the underwater vehicle 4 (UV). <...> As a result of parametric interaction of the horizontal component of the electric fi eld E1x with a power fl ux of the acoustic radiation of frequency fa the residual signal of frequency F = fe of frequency fe – fа is formed in the skin layer of the E-fi eld radiation falling onto the surface. <...> Subject to validity <...>
