In the "fields" model, the signal propagates from left to right as an electromagnetic wave in the dielectric, inducing current density waves in conductors subjected to those waves (both signal and "ground," or any other adjacent conductor).

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.

Understanding differential pairs and differential signals: just don't think "differential mode." It will help keep differential signals separate from odd mode impedance, eliminating the confusion

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.

AS A churchman, I have to agree with the proposition that early exposure to overt sexual behaviour is detrimental' but I have to take issue with the final paragraph of Beryl E Murphy's letter, "the whole of the purpose of the sexual act is merely to propagate a species".
