As [partial derivative]U/ [partial derivative]z approaches zero, the ray exits the dipole and slowly propagates rightward, as dictated by the positive horizontal wavenumber.
This current loop propagates down the loop, always flowing between the signal and return sides of the loop until it encounters the end of the loop, which is the light bulb.
It defines a voltage pattern that would propagate undistorted down the line, an impedance of each line when in that mode and a speed of the signal that propagates in that mode.

Establishing commercial plantations will cost a good chunk of money, since a grower would not want to propagate wild yew material, which is highly variable in chemical content, but would want lead or selected material with high concentrations of paclitaxel.
However, because of differences in species biology and economic and social systems, the methods used abroad to propagate eucalyptus and other species do not work well with loblolly pine in the United States or are not attractive economically.
The cracks initiate at localized stressed sites and then propagate through the material, typically following the steers grain boundaries.
Virtually all plants, including vegetables and herbs, will propagate from seeds or berries, unless they're from sterile, hybrid stock.
