... 3. What is plane wave? Is a plane wave transverse? Why? Please prove that the plane wave propagates in a conductive medium is transverse. (20%) 4. The Poynting vector is defined as S = E x H. For a wave propagating in a conductive medium, whether the electromagnetic energy flows into the volume is ...

TAP 130- 2: Exponential changes
... Many naturally occurring changes are exponential. That is, they follow a pattern in which equal steps result in equal fractional changes. The following are just some of many possible examples. Attenuation of electromagnetic radiation as it travels through a material (e.g. light in a glass fibre). Eq ...
