V l longitudinal wave velocity e modulus of elasticity r density m poisson s ratio more information. If i look at the formula without the n factor and look at my old krautkraemer ut slide ruler i see the formula for the skip distance like this 60 2 x tan beta 3 5 70 2 x tan beta 5 5. The frequency of operation has a major influence on the skip distance that can be achieved.

For a flat earth skip distance is given as. Ultrasonic formula longitudinal wave velocity shear wave velocity wavelength where. Skip distance skip zone in figure 2 19 note the relationship between the sky wave skip distance the skip zone and the ground wave coverage.

Skip distance is defined as the minimum distance from the earth s surface and the point from where the radio signal is been transmitted. Typically as the frequency increases a lower angle of radiation is needed to return the signals to earth in a shorter distance. Q r refracted sound wave angle.
