{ "item_title" : "Investigating the Use of Frequency Selective Surfaces in High Power Microwave Applications", "item_author" : [" Steven Pugh "], "item_description" : "This thesis explores new territory with the theoretical investigation of the use of FSS in HPM applications. Work was performed in a simulation environment where rectangular and ring-shaped FSS elements were evaluated. Incident electric field levels of 0.5MV/m were propagated toward the FSS in a plane wave that was perpendicular to the surface. Results show that the total electric field in the apertures of the FSS can reach more than 6MV/m. This necessitates the use of high strength dielectric materials surrounding the FSS to reduce the risk of electrical breakdown. It is shown that a dielectric of only 2.5mm thick on each side of the FSS eliminates the risk of breakdown.", "item_img_path" : "https://covers2.booksamillion.com/covers/bam/1/28/832/454/1288324545_b.jpg", "price_data" : { "retail_price" : "57.95", "online_price" : "57.95", "our_price" : "57.95", "club_price" : "57.95", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
