New B-2 repair method saves the US Air Force millions

The B-2 Spirit has always been one of the most expensive aircraft the United States has ever built, and for years a serious mishap could quietly threaten to erase a bomber from the inventory. Now, a ...
Abstract: A fast and accurate frequency sweep method combining the mixed finite element method (MFEM) with the second-order Arnoldi algorithm is proposed to characterize the EM material properties for ...
