Microwave heating at the electron-cyclotron frequency has been effectively employed to heat plasmas confined in open and closed magnetic confinement geometry where the applied heating frequency was near or above the plasma frequency. The earliest experimental investigations demonstrated the effectiveness of plasma electron-cyclotron heating (ECH) and later theoretical work validated these observations. In this review, we briefly consider some of the more relevant ECH propagation processes and heating mechanisms. Results are presented from some of the more recent toroidal ECH experiments, including tokamaks, but principally from the ELMO Bumpy Torus (EBT). In the last section, we discuss the technological considerations so important to successful applications of ECH to plasma experiments.
