Thus, the quaternionic Maxwell equation and continuity equation predict that there exist a scalar wave propagating with speed of light.
He explains such key concepts as the method of moments, finite difference time domain, the finite element method, and Green's functions, with an emphasis on the analysis of the scalar wave equation in Cartesian coordinates.
This method for the scalar wave equation was proposed in [1] and is a combination of ideas presented in [5, 7].

Then, its wave structure is easily found as a solution of the scalar wave equation to get a quantum-wave electron that is based upon only two fundamental principles of Nature.

After 1945, the next step in research on wave structure was taken in 1985 when the present author, (7,8) proposed a scalar wave equation with spherical quantum wave solutions, as a basis for the Wave Structure of Matter.
