Furthermore, it is important not only to explore new ways Optimization is an essential process in several business, Chloride XeCl pulsed laser. Because this laser functions in the student was Angie Lopez, of developing these technologies to be more compact and cost efficient, management, and engineering applications to make systems that Ultra Violet range of the electromagnetic spectrum, the beam a young lady from St. but also it is important to explore the combination of all the facets of function to the fullest of their capacity. During this internship, we is invisible to human eyes and can cause tissue damage if Mary’s Academy. Who, by these advancements to find an optimized state. optimized the function of a circulator, a three-port device used to exposed. For this reason, caution must be used at all times in the end of her internship The Space and Naval Warfare Systems (SPAWAR), San Diego, simultaneously send and receive signals through a single antenna. the lab, especially in processes such as ablation, where a created a small hologram, more locally known as SSC-Pacific, works to promote innovations that The objective is to create a circulator with maximum isolation material is superheated into a molten substance and small assembled a computer, set aid the United States Navy and Department of Defense (primarily in (separation of signal levels) and minimum insertion (loss of signal up a laser communication particles are ejected off the surface. We use this process to the area of communication). power over the frequency band.) system, and learned the form particles in the micro level with a spherical shape so that In the Advanced Technology Branch at SSC-Pacific, projects are Multi-objective Optimization refers we can couple light around them. Below are ablated samples fundamentals of waves, geared toward optimizing processes, the use of fiber optic optics, and chemistry. to a set of acceptable trade-off optimal of silicon seen using an scanning electron microscope (SEM). communication, and the development of technology in the micro and nano level with the use of lasers. Mentorship and outreach is very solutions called a Pareto front. A solution belongs to the Pareto set if there -Results- After running the GAM much a part of the mission at is no other solution that has a lower and PAL methods four times SPAWAR because for these value. Minimal points can be found with based on the 6 local minimal innovations to continue in , optimization methods, such as the Goal points of a random 100 points, it is extremely important Attainment Method (GAM) and the we found 40 Pareto minimal for the next generation to Point and Line Method (PAL). points, chose one point, and be inspire to lead in the We estimated the Pareto point found out the matrix that years to come. During this for multipart transformers represents the turns ratios of internship we had the opportunity to matching our 81 MHz circulator. that circulator. explore the projects in progress at SPAWAR, such as The transformers are After the spheres are fabricated circulator optimization and coupling light around parameterized by the 9-element in the laser lab, light can be turns ratios. The turns ratios are In regards to the laser, unfortunately, the gases particles, to co- mentor high school interns, and to help coupled around the sphere represented by a 3x3 matrix, and used to generate the laser were consumed near the end organize outreach events. In this way, we were able because the internal reflection of the ratio of the number of turns of the internship and we could not fabricate more to experience the full cycle of how technology is the surface on the sphere can affects isolation and insertion.. micro spheres.
