Abstract: By formulating and solving the adjoint equations governing the beam–wave interaction in a traveling-wave tube (TWT), we show the partial derivatives with respect to design parameters of ...
Abstract: Explicit formulas for converting spherical wave expansions with vector basis functions and scalar expansion coefficients into spherical wave expansions with scalar basis functions and vector ...
The implications of quantum mechanics suggest reality isn't as solid as we think it is, but physicist David Bohm had a spin ...
