Letâs take a look at some answers: 1  Architecture roles are generally differentiated by some level of solution-specific expertise in one area or another. 2  This could involve methodology, toolsets, skill sets or even industry domain knowledge.
Definition. A vector field on two (or three) dimensional space is a function that assigns to each point (or) a two (or three dimensional) vector given by (or). That may not make a lot of sense, but most people do know what a vector field is, or at least theyâve seen a sketch of a vector field.
E is the electric field vector, and B is the magnetic field vector of the EM wave. For electromagnetic waves E and B are always perpendicular to each other and perpendicular to the direction of propagation. The direction of propagation is the direction of E x B. If, for a wave traveling in the x-direction E = Ej, then B = Bk and j x k = i. Electromagnetic waves are transverse waves.
