In this work, to characterize the radiated emission from electronic circuits in shielding enclosure, an improved electric dipole-based source reconstruction method (SRM) is developed. Moreover, by resorting reconstructed equivalent source, estimation of electromagnetic interference (EMI) between different circuit modules enclosure can be conveniently and accurately evaluated. Different free-spa...

The author for the first time reproduces and interprets tamga-like other signs on silver vessel, found by V.D. Kubarev in 1976 early medieval memorial enclosure valley of river Yustyd South Altai. In all 12 were carved half them make two groups. One includes tamgas Ashina dynasty Turks-togyu form a goat figure, is Karluk shaped as an acute angle. Other probably belonged to Tiele tribes. sign, b...

A transonic air stream flowing over a rectangular cavity or enclosure is unsteady. At certain flow conditions, large scale oscillations develop in the shear layer which, for an open cavity, spans across the whole enclosure. The convected shear layer instabilities interact with the cavity geometry, they generate resonance, and induce large amplitude wall pressure fluctuations, aerodynamic pressu...

This study evaluated the manufacturing of metal–polymer hybrid parts using a 3-axis desktop Fused Filament Fabrication (FFF) printer. Two printing strategies were employed: more trivial one, consisting 3D-printing polymer directly onto metal surface, and an alternative encasing with printed polymer. Materials used Ti-6Al-4V (both rolled/sandblasted 3D-printed by laser powder bed fusion) polyami...

Title of Dissertation: ANALYSIS AND MITIGATION OF ELECTROMAGNETIC NOISE IN RESONANT CAVITIES AND APERTURES Lin Li, Doctor of Philosophy, 2004 Dissertation directed by: Associate Professor Omar Ramahi, Mechanical Engineering The trend of low voltage in electronics circuits and boards makes them vulnerable to electromagnetic interference (EMI). Furthermore, higher speed (clock rate) leads to fast...

This study analyzed that the penetration of electromagnetic waves through an unknown opening in a large enclosure generated standing within enclosure, thereby reducing its shielding characteristics. A 3D numerical analysis confirmed performance can be improved by using absorbers to reduce wave. was verified experimentally.
