A quasi-chirped technique is applied to the engraved grooves in the surface of the MIM waveguide, and a new kind of broad-bandgap SPPR is achieved. Meanwhile, by optimizing the profile of gap width between the metal …

Web19 mei 2007 · The study of millimeter-wave low sidelobe linear arrays with time modulation technique is presented in this paper. Special emphasis is on the realization of low sidelobes with uniform amplitude excitations, which are easier for the practical implementation. Two types of time modulated linear arrays with uniform amplitude excitations, namely, the … WebWe note that a sidelobe pattern with minima and maxima separated by 1 would appear at ℓ ∼ 180, with lower ℓ representing sidelobe variations at larger angular scales. A mask is applied to the maps to isolate the sidelobes that could … how fix microsoft edge
