We show that the trajectory of a point charge in a uniform electromagnetic field is a helix if the Lorentz equation governs its motion. Our approach is totally relativistic, and it is based on the use of the Frenet-Serret formulae which describe the intrinsic geometry of world lines in Minkowski spacetime.
An analytic method to probabilistically predict the electromagnetic coupling in multiconductor transmission lines is described. This method is based on the a priori application of minimum information (maximum entropy method MEM) of the random properties of the geometry of the multi conductor transmission lines and of the excitation signals. This model was used to analyze the electromagnetic coupling...
