Study and design of a quasi-optical mode converter for W-band whispering-gallery mode gyrotron
W波段边廊模回旋管准光模式变换器的研究与设计

A quasi-optical mode converter for a whispering-gallery mode gyrotron,consisting of a Vlasov helically-cut launcher and two curved-mirror reflectors,is studied and designed.Firstly,the operation mechanism of the Vlasov type quasi-optical mode converter is investigated using geometric optics theory.And then,applying the aperture field integration and the surface current source integration of the vector diffraction theory,a numerical simulation code is programmed.Finally,the code is used to study a quasi-opti...
