Slow-wave structures are useful in shrinking electrically-long elements. In microwave engineering, cost is a linear function of circuit area, so any tricks we can employ to shrink designs are worth knowing about. One of the applications of slow-wave circuits is in time delay networks. Let's start the topic by … Visa mer This class of circuits are related to "artificial" transmission lines (an artificial transmission line uses lumped inductors and capacitors that obey the telegraphers equations). Note that there are many physical … Visa mer In the case of transmission lines, the onset of a stop band for electromagnetic waves in a periodic structure corresponds to Bragg reflection in crystals. In 1915, William Henry Bragg … Visa mer This type of slow-wave structure is less well known. Silicon is usually a very poor insulator.
