The purpose of this research endeavor is to devise ferrite materials for microwave, self-biased circulator applications. To this end, the research team focused on two key activities. The first was the development of a ferrite/epoxy composite that can be directly injected into a dielectric substrate. As the ferrite cured, two external magnets were placed on both sides of the ferrite to align the ferrite moments; once cured, the moments were ...
The questions that are being asked in this investigation are: (1) once an ELF signal is generated, how far does it propagate and still be detectable and (2) how can such signals be modeled, excited and measured? To this end, the scenario considered is one in which an ELF source of the electric or magnetic kind is located in or above water, such as a lake or ocean. This source ...
