Abstract:
This paper presents a numerical analysis of a ridge
gap waveguide. Ridge gap waveguides belongs to a new
metamaterial-based waveguide technology for millimeter and
submillimeter waves which emerged recently. The magnetic
boundary condition or high-impedance surface (ideally a PMC)
has been realized by means of a bed of nails as parallel-plate
mode killer. Field plots of the ideal PEC-over-PMC ridge gap
waveguide are presented, as well as when the PMC is realized by
the bed of nails. The quasi-TEM mode shows an octave useable
bandwidth for the bed of nails case.
