Abstract
In the above paper, the author presents the theoretical analysis of a single-ended Class E/Fn mode with explicit derivation of the idealized optimum voltage and current waveforms and load-network parameters with their verification by time- and frequency-domain simulations for a particular case of Class E/F3 mode with a 50% duty cycle. However, some errors have been found which may affect the readers understanding, and they will be clarified in this letter.
