Abstract: Calculating how electromagnetic waves propagate in spherical media is currently approached in two ways: by using eikonal equations based on a spherical coordinate system or by using ...

Spheres have always been seen as a rather fantastical form for a building. Yet the sphere is in a geometric sense the most efficient form there is – and new technical innovations are making it easier ...

Investopedia contributors come from a range of backgrounds, and over 25 years there have been thousands of expert writers and editors who have contributed. Vikki Velasquez is a researcher and writer ...

Abstract: Fast adjustment method of spherical aberration and focus offset by elliptic equation was developed. In the case of Blu-ray disc™, spherical aberration is increased because of high NA optical ...

Parameters of FCNN-based XC potential and codes to call them (.py). PySCF, Pytorch, tqdm and Optimized Einsum packages are required to run the example codes. Compile the sh.f90 file to get the ...

Internal planetary field code from spherical harmonics, in IDL, MATLAB and Python. This is part of a community code project: Magnetospheres of the Outer Planets Group ...
