FREQUENCY SELECTIVE PROPERTIES OF COAXIAL TRANSMISSION LINES LOADED WITH COMBINED ARTIFICIAL INCLUSIONS

The properties of a modified coaxial transmission line by periodic inclusions will be discussed.The introduction of split Fume Extractor ring resonators, conductor stubs, air gaps, and combination of these gives rise to new frequency selective properties, such as stopband or passband behavior, observable in planar as well as volumetric metamaterial

The paper develops a method to choose the number of rotor bars in order to eliminate rotor slot harmonics in stator current spectrum and pulsation torques that are their consequence.Mains-fed, Default three-phase cage induction motors with the most common number of pole pairs and number of stator slots, that result in integer slot winding, are anal
