Shielding Effectiveness of a Lossy Metallic Enclosure

In this paper, shielding effectiveness (SE) of a perforated enclosure with imperfectly conducting walls is evaluated. To this end, first, an accurate numerical technique based on method of Moments (MoM) ispresented. In this method, lossy metallic walls of the enclosure are replaced by equivalent electric surfacecurrent sources. Then, the impedance boundary condition on the imperfectly conductin...

Isoperimetric Triangular Enclosure with a Fixed Angle

Given a set S of n > 2 points in the plane (in general position), we show how to compute in O(n) time, a triangle T with maximum (or minimum) area enclosing S among all enclosing triangles with fixed perimeter P and one fixed angle ω. We show that a similar approach can be used to compute a triangle T with maximum (or minimum) perimeter enclosing S among all enclosing triangles with fixed area ...

Lightning Responses on a Finite Cylindrical Enclosure

The voltage on a single-turn loop inside an enclosure characterizes the enclosure shielding effectiveness against a lightning insult. In this paper, the maximum induced voltage on a single-turn loop inside an enclosure from lightning coupling to a metal enclosure wall is expressed in terms of two multiplicative factors: (A) the normalized enclosure wall peak penetration ratio (i.e., ratio of th...

Enclosure 3 - Strontium

Strontium (atomic symbol Sr) is a silvery-white alkaline earth metal that exists in several stable (e.g., Sr-86 and Sr-88) and several radioactive (e.g., Sr-89 and Sr-90) isotopic states. Stable strontium and its salts have many industrial uses, such as providing the red color in pyrotechnic devices such as tracer bullets, distress signal rockets, flares, and fireworks. In medicine, strontium b...
