7.1: TEM Waves on Structures

Equation (7.1.18) defines the characteristic impedance Zo = (cC) − 1 = √L / C for the TEM line. Both the forward and backward waves alone have the ratio Z o between v and i, although the sign of i is reversed for the negative-propagating wave because a positive voltage then corresponds to a negative current.

SEM vs. TEM: Understanding the Key Differences and …

SEM offers the best quality images of a sample's exterior, capturing its texture and composition with depth. It does this by directing a focused beam of electrons across the surface, collecting the emitted signals to form an image. In contrast, TEM provides a window into the sample's interior, achieving higher-resolution images that can display ...
