... As elegant a solution as a Salisbury Sheet is, its limitations are obvious. It only works at one frequency. In order to make the Salisbury Sheet work over a larger range of frequencies, several sheets can be used as shown in Figure 4. Here sheets of different surface resistivities are placed at one- ...

Maximum Power Transfer in a Circuit
... This derivative is equal to zero when R = Rint. From the above discussion it is clear that the derivative is zero here because this is the value of the resistance R at which the power P is a maximum (as opposed to say a minimum).
