WebThe transmission electron microscope (TEM) operates on many of the same optical principles as the light microscope. The TEM has the added advantage of greater resolution. This increased resolution allows us to study ultrastructure of organelles, viruses and macromolecules. Specially prepared materials samples may also be viewed in the TEM. Web1 Nov 1990 · The influence of transverse electromagnetic (TEM) waves on dielectric encapsulated semiconductor devices is not attracting engineers' attention. It is found that the parameters of dielectric encapsulated semiconductor devices may degrade when these devices are radiated by TEM waves even though they are open circuited. Our experimental …
