Abstract: Resistors, Inductors and Capacitors are common electrical circuit elements. They are easy to design and readily available for use at low frequencies (up to a few MHz). As we increase the frequency to 10’s and 100’s of MHz, these elements tend to have complex equivalent circuits. New approaches are needed to make them work efficiently at high-frequencies. In addition, in high-power EMs (HPE) applications, we are also concerned about arcing and breakdown issues within and across these components. In this talk, we review certain methods of building electrical components (R, L and C) specifically for HV and HF applications. It is well known that high-frequencies and high-voltages impose conflicting requirements. High-voltage applications require increased inter-electrode distances, while high-frequency operation requires dimensions to be small. If we consider the feed point of an antenna, high-voltage argues for more space, while high-frequencies require smaller spaces. Furthermore, we require R, L and C elements for many HPE applications such as elements of pulse-shaping networks and terminators for transmission lines. They are also needed in the design of high-performance EMC filters. In this presentation, we discuss how R, L and C elements can be built for both high-voltage and high-frequency applications.
