In this paper the positive and strictly contractive extension problems for almost periodic matrix functions are treated. We present necessary and sufficient conditions for the existence of extensions ...

Abstract: A class of Boolean functions arising naturally from a consideration of the periodicities of multithreshold functions is defined and the basic properties of these functions, the completely ...

Abstract: The comparison between periodic function space based power theory and three other power theories including traditional power theory , instantaneous power theory put forward by Akagi and ...

This work, part II in a series, presents an efficient method for evaluation of wave scattering by doubly periodic diffraction gratings at or near what are commonly called 'Wood anomaly frequencies'.

This paper covers the concept of Fourier series and its application for a periodic signal. A periodic signal is a signal that repeats its pattern over time at regular intervals. The idea inspiring is ...
