Senior Design Team sdmay22-39 • Fast, Compact, High Strength Magnetic Pulse Generator

Summary

The goal of the project is to design and fabricate a device that can speed up signals in optic cable applications via the use of high speed magnetic pulses and magneto-optic material. The device will be capable of producing magnetic field pulses greater than or equal to 500 gauss within 100 nanoseconds, will be powered by a source voltage of less than or equal to 15 Volts DC, and will be less than 3.5” by 2” in physical size. Given the design requirements and resources from the previous iterations of this project, we plan to create an improved design including a reduced rise time of 10ns, functional programmable control of the magnetic field generation, reduced overall noise, and increased stability.

Application

This device will be used in networking systems to increase the bandwidth of the system by using magneto-optic switching. This concept uses Faraday effect, which is a change in the polarization of the travelling EM wave caused by optic cable caused by an outside EM field. Since this switching is faster than current systems used, we can achieve a larger bandwidth in our network. For the users of this system, since the bandwidth is larger and can host more users, this system will be cheaper. A similar example is how current internet systems are switching to fiber optic systems.
