The spot size of the focus in a very lossy medium is discussed with relevance to creation of local temperature increase in muscle tissue by means of electromagnetic waves. A slot in a cylinder is used as a source for heating a lossy cylinder and the internal fields are analyzed by a modal method and a fast Fourier transform (FFT) method.
