1. A method for treating a carbon or ceramic yarn comprising forming a coating on the yarn in a reaction zone of a reactor by heating a segment of the yarn in the presence of a gas phase in a microwave field, wherein the gas phase comprises a mixture of a diluent gas and a coating precursor in the vapor state, and wherein the gas phase is formed at least by introducing the diluent gas into the reactor, said introduced diluent gas being mixed with liquid coating precursor as it is introduced into the reactor before the reaction zone, wherein the diluent gas bubbles in said liquid coating precursor and is introduced into the reactor below a meniscus of said liquid coating precursor.
