Scatered and incident voltage

incident voltage

When studying English literature about lightning induced overvoltages, I came up with terms "scattered" and "incident" voltage / em field. I can't figure out, what exactly these terms mean. Which voltages / fields are these? Can somebody please help me with explanation. Thanks.

scatered

Hello
Sloncek
The words simply mean fallen and spread on falling.
The term incident means fallen on a surface. Surface is important.
Example: In Photo cells current o/p is proportional to the light incident on the photo sensitive surface,
Scatter means to spread in a random or pseudo random manner.
When energy falls on some particles (important) it is deflected. The flow pattern changes. It will be spread. example X-rays are scattered by metals.

incident scattered voltage

I cannot access those papers, but it seems they're about transmission lines. Do you mean the reflected and incident voltage?

scatered means

The incident voltage is a super set sloncek
It consists of the scattered voltage and reflected voltage.
That is when you have V incident volts It breaks up into say R volts of reflected and S volts of scattered potential.
