A semielliptical trench flush-mounted under a metal plane and filled with double-negative (DNG) metamaterial is considered. The primary field is an electric line source parallel to the trench and located inside the trench or in the half-space above it. The two-dimensional boundary-value problem is solved exactly in terms of infinite series of elliptic-cylinder wavefunctions. In particular, the far...
The paper reports the results of a systematic improvement project on the thermal cycle (TC) lifetime prediction of BGA memory modules with SnAg1.0Cu0.5 and SnAg1.0Cu0.5Ni0.05 solder alloys. The pre-existing lifetime modeling scheme allowed predictions with an inaccuracy factor of about 1.6plusmn1 on average while in TC experiments, the characteristic lifetime, N63, showed a standard deviation of about...
The proposed method pertains to diagnostics of linear parts of gas distribution and trunk lines. It is based on nanolevel effects on the work surface of pipes. The proposed pipe wall diagnostics technique allows taking consequent analyses reasonably by piecemeal removing and cutting specimen during 20-30 years of pipeline operating time. It ensures the accurate predictive analysis of the pipeline...
Summary form only given. Processing of materials in high power microwave field is unique in many ways. The process is fast, energy efficient and environment friendly. Wide variety of materials, such as, insulating ceramics, semiconductors, metals and metallic compounds have been microwave processed. In many situations, it offers choice to choose an appropriate processing route. Materials, for example,...
Solid state electronic industry uses large quantity of ultra pure water (UPW) and generates huge volume of wastewater bearing a wide range of acids, hazardous and toxic organic inorganic chemicals and heavy metals. It also emits vapours of several organic compounds used as solvents etc into air. Thus the industry is facing serious environmental problems and is making all possible efforts to reduce...
