In other words,capacitive network of winding acts on incoming waves so dramaticaly that degenerates formation of standing waves' notches and nodes. After critical high frequency passed,voltage profile over winding could be just a sort of hyperbolic function and nothing more ,appearing and dissapering in phase with driving source voltage function.
