Radio Wave Propagation: An Introduction for the Non-Specialist
3.6, the penalty is a zone out from the transmitter, known as the skip distance,
within which a signal cannot be received. Nevertheless, it is useful now to
determine an expression for the highest frequency for return at a given angle of
incidence: ...

Non-Destructive Test And Evaluation Of Materials
Skip distance S is the distance between two nodes and is given by 5 = 2t tan</>,
where <p = refracted angle, S =
skip distance and t = specimen thickness (b) Two
lines are drawn from the central axis of the weld bead, one at a distance of 5/2 ...

Antenna And Wave Propagation
8.4 SKIP DISTANCE Skip distance is the distance from the transmitter where the
HF waves after reflecting from ionosphere reaches the earth's surface back. The
skip distance depends upon the angle of incidence, the degree of ionization, and
...

Antennas and Wave Propagation
Skip distance (ds) It is defined as the shortest distance from the transmitter that is
covered by a fixed frequency (> fc). When the angle of incidence is large, ray 1 (
Fig. 9.24) returns to ground at a long distance from the transmitter. If the angle is ...

Nondestructive Evaluation: A Tool in Design, Manufacturing ...
While this may be estimated through trigonometric calculations with a correctly
calibrated probe, it is assuring to confirm the settings and parameters by first
establishing the skip distance S for the inspection. The skip distance S is the
distance ...

Practical Non-destructive Testing
In this case, the probe is manipulated along a line parallel to the edge at a
distance estimated to be equal to the skip distance 5. The skip distance may be
estimated using the specified probe inspection angle. Once the skip distance is ...
Baldev Raj, T. Jayakumar, M. Thavasimuthu, 2002
Concept of skip distance. f > fcr we, therefore, do not have reflected wave within
certain distance. The minimum distance from the transmitter over which the
reflected wave can reach is called the 'skip distance'. The ionospheric
propagation is ...

Underwater Acoustic Modeling: Principles, techniques and ...
Based on the depth of the surface layer and the water depth, a single effective
skip distance (H) is formulated. Multiples of this effective skip distance are used to
define a zone of direct ray paths (20 log R, where R -is the range), a zone of ...

Antennas and Wave Propagation
7.12 Skip Distance The skip distance is the shortest distance from the transmitter,
measured along surface of the earth, at which a sky wave of fixed frequency will
return back to the earth. The angle of incidence for which the wave returns back ...
