  • Patent number: 5123868
    Abstract: A method of forming a electromagnetic radiator having cavities of predetermined dimensions involving coating a plurality of wires with an electromagnetic radiator material at predetermined thicknesses, the wires being soluble in a solvent and the radiator material being insoluble in the solvent, forming a bundle of a multiplicity of the coated wires, the coatings on the wires engaging each other, reducing the diameter of the bundle to a smaller predetermined diameter and fusing the coatings together with metallurgical bonds through the reduction thereby uniformly reducing the diameter of each of the coated wires and thicknesses of each of the coatings on the wires in the bundle, slicing partially through the fused bundle at predetermined regular intervals whereby to define the depth of the cavities, chemically removing the wires from inside the coatings whereby to form a foraminous electromagnetic radiator having an array of cavities of predetermined lengths and diameters formed by the drawn coatings.
