Helen McLean,Soumitri Varadarajane study of the static magnetic field. But what exactly is a magnetic field? This question will be answered gradually, but, for a simple description, we may say it is a new type of force field in the same sense that the electric field is a force field. Take, for example, a magnet. It attracts or repe

The reflection coefficient was used to find the conditions on the line, to calculate the line impedance, and to calculate the standing wave ratio. Voltage, current, and power were all related to the reflection coefficient. The reflection coefficient, in turn, was defined in terms of

Starting with ., we assumed that a wave was generated in some fashion but did not concern ourselves too much with how the wave was generated. Occasionally, the term “source” or “antenna” was mentioned but only to indicate that the wave must have a sourc
