Hence, the water surface in the center of the column rises and falls with the same period as that of the
external wave.
This is due to the additional force of the
external wave acting on the plasma, which is altering the rotation of the electrons with respect to the one induced solely by the magnetic field.
Data used to characterize the
external wave regime affecting the study area were supplied by the ODIN programme (SMC) and obtained from the Bilbao external buoy records (Spanish Port Network; http://www.puertos.es/).
The critical contributions of Schelkunoff were to formulate transmission through a wall -- long before the Radiation Laboratory work -- and to recognize that near-field effects could be subsumed into the
external wave impedance [Z.sub.wave].
The top of each panel was continuously welded to the existing structure to resist the
external wave force from storms and to hold its own weight.
If we cannot shape the future ourselves, we must position to ride the
external waves that will.
