An efficient mode solver for the cross-section mode of three-dimensional bent waveguide is proposed and validated. The technique is based on vectorial slab mode expansion and perfectly matched layer ...

In the cylindrical coordinate system, a cylindrical Hankel integral transformation is adopted to expedite the integration of the tensor Green's functions from the spectral domain to the spatial domain ...

Mathematics is the universal language of science while computer science is the study of the hardware and algorithms that are used in modern computer systems. Since many of the early pioneers of ...

When people think of DNA, they usually think of genes, the parts that code for proteins and drive inherited traits. But there ...
