SOME APPLICATIONS OF NANODIMENSIONAL FUNCTIONAL LAYERS IN SHIP ELECTRONICS

Nanostructured materials have a number of desirable thermal, electromagnetic and mechanical properties and can play a significant role in improving key parameters of the ship electronic equipment.

Our recent work consist the obtaining of resistive elements, formed upon electroinsulated plates of alumina ceramics with nanodimensional conductive layers.
Different layer compositions are experimented and the change of the electrical resistance due to the temperature rate is studied. The elements are applied as sensors in electronic bridge circuit for positive temperature measuring. In recent years, nanoscaled magnetic materials have received much attention too, due to the fundamental interest in the unique magnetic property different from that in the bulk phase and to their promising applications in technology such as in the high-density magnetic storage.

The magnetic properties are usually dictated by the size, dimension, shape, structure, morphology of the constituent phases, along with the type and strength of magnetic coupling between them. The magnetic metals, including Fe, Co, Ni, and their related alloys in low dimensional form, are one of the most important subjects to study. Nanostructured materials can improve key antenna parameters like radiation-efficiency, directivity and mechanical robustness. Electromagnetic absorption properties can be controlled by changing the particle size distribution in nano-materials and application-specific, tailored materials can be produced.
