Waveguides and RF Cavities
In the previous chapter we studied propagation of electromagnetic waves in free space. Free space is an idealization which can be used when the waves propagate far from material boundaries. If this is not the case, one has to take into account the interaction of the electromagnetic field with the medium. In this chapter we will study one example that is especially important for accelerator applications, when the medium can be modeled as a perfectly conducting metal whose boundaries reflect the electromagnetic field without losses. The impact of resistive losses can often be treated perturbatively, as we have seen in Chap. 12. We will consider cylindrical waveguides and resonant cavities. We will also discuss how cavity eigenmodes can be excited by relativistic beams of charged particles.
