(under subclass 592.1) Process for making a device which either transmits, delays, or attenuates electrical wave energy by series of material boundaries dimensionally related to the frequency of the wave energy.
(1) Note. Some conductors are capable of transmitting other electrical currents as well as radio wave current. A process of making such a conductor is placed here only if it involves a parameter of construction which is wave energy dependent, i.e., frequency dependent. If no wave energy parameter is present, a method of producing such a conductor is placed in subclasses 624+, below.
