The Design And Construction Of A Radio Telescope, Avery Elizabeth Bunting, Kira Hope Tolman
Architectural Engineering
Two architectural engineering students and an electrical engineering student worked together to design and build a radio telescope that is capable of using hydrogen line astronomy to map the galaxy. The telescope is made entirely out of aluminum, which, combined with small deflection limits, made for an iterative design process that focused primarily on constructability and supporting the desired outcomes of the electrical side.
Shielding Effectiveness Of Superalloy, Aluminum, And Mumetal Shielding Tapes, Cindy Suit Cheung
Shielding Effectiveness Of Superalloy, Aluminum, And Mumetal Shielding Tapes, Cindy Suit Cheung
Master's Theses
Using MIL-HDBK-419A, MATLAB and Nomographs, Shielding Effectiveness for the Magnetic Field, Electric Field, and Plane Wave were calculated over a frequency range from 10 Hz to 1 GHz. The three shielding tapes used included superalloy, aluminum, and mumetal. Calculations for Shielding Effectiveness involve the computation of Absorption Loss, Reflection Loss, and Re-Reflection Correction Factor. From the outcome of the calculations, it was suitable to conclude that all three metals fulfill the 40 dB Shielding Effectiveness requirements for SGEMP fields for frequencies greater or equal to 1 MHz. Accordingly, all three shielding tapes provide at least 40 dB of shielding to …
