Deduction of the De Broglie's relation λ=h/p from the classical electrodynamics

It is well known that De Broglie enables the use of the relativistic mechanics and –depending on a number of assumptions– to discover his relation λ=h/p, which led further to the creation of the theory of quantum mechanics (QM). However, after De Broglie's approach famous contradictions have appeared between De Broglie's theory and the Special Relativity Theory, also there were a number of suggestions in order to solve these contradictions. According to the suggested method in our papers it was remarked a serious part of the contradictions, and by following this method, we will present a new approach to derive the relation λ=h/p, starting from classical electrodynamics without any contradictions between Special Relativity Theory (SRT) and De Broglie's theory.
