surface wave

[′sər·fəs ‚wāv]
(communications)
(electromagnetism)
A wave that can travel along an interface between two different mediums without radiation; the interface must be essentially straight in the direction of propagation; the commonest interface used is that between air and the surface of a circular wire.
(fluid mechanics)
A wave that distorts the free surface that separates two fluid phases, usually a liquid and a gas.
(mechanics)
(oceanography)
A progressive gravity wave in which the disturbance is of greatest amplitude at the air-water interface.

Some of these problems are reduced by signals that do not reflect off the ionosphere, such as line-of-sight signals with small coverage areas, and groundwave signals in the low frequency (LF) part of the radio spectrum below 300 kHz.
With ranges extending from groundwave to 1,000 km from the system, DRAGONFIX can amply provide coverage of tactical areas of influence and interest up to EAC, in both traditional and nontraditional missions.
C) Radio skywaves bend as they pass from one atmospheric condition to another, and groundwaves likewise bend as they pass from one conductivity to another.
