The basic features of microwave propagation and electron-cyclotron damping in ELMO Bumpy Torus (EBT) devices are investigated to provide an understanding of the heating of the toroidal core plasma component. The characteristics of microwave propagation in EBT geometry, where there is strong variation of absolute value B along field lines, are described and contrast is made with the electron-cyclotron heating (ECH) of tokamaks. Linear cyclotron damping calculations are presented for plasmas having parameters typical of EBT-I and parameters projected for EBT-II. It is shown that tye extraordinary mode is completely absorbed near the fundamental cyclotron resonance when propagating from the high magnetic field side (mirror throat).
