The invention relates to a method for designing a radio-frequency cavity, in particular to be used in a cyclotron, radio-frequency cavity () comprising a conductive enclosure or 'liner' () connected by at least two essentially inductive elements or 'stems' () to a capacitive electrode (), the method being characterized in that it comprises the following subsequent steps: A. subdividing the volume of said radio-frequency cavity () in a number of sub-cavities () corresponding to at least two stems (), each sub-cavity comprising a respective (stem); B. imposing a condition of magnetic orthonormality on the separation surfaces between said at least two sub-cavities (); C. independently for each of said at least two sub-cavities (), calculating the size and/or the position of the respective stem () with respect to the physical conditions at the boundaries. The invention further relates to a radio-frequency cavity realized using the method according to the invention, and a cyclotron using such a cavity.
