The disclosure pertains to a method of orientating particles by their easy axes in a selected area of a composite comprising the particles dispersed in a matrix. The method comprises liquefying and then solidifying the matrix at the selected area while applying an external magnetic field on the composite. The composite can be used for a transmission line component for directing high frequency electromagnetic waves. The particles are preferably superparamagnetic nanocrystallite particles and matrix is preferably a polymeric material.
