background: health-related quality of life is affected by electromagnetic field exposure in each person everyday life. however, this is extremely controversial issue. objective: investigation of the associations between electromagnetic field exposure and miscarriage among women of tehran. materials and methods: in this longitudinal study, 462 pregnant women with gestational age <12 wks from sev...

Under the condition of specific pulsed discharge parameters, mode conversion low-temperature plasma jet channel that originally propagates along a straight line will occur, forming three-dimensional helical channel. Unlike traditional wave discharge, there are no factors such as an external constant magnetic field destroys poloidal symmetry dielectric tube, and chiral direction streamer change ...

In this paper, a D-dot electric field sensor and a fiber-optic transmission electric field sensor are developed for measurement of electromagnetic pulse. The D-dot sensor is a differential model sensor without source and has a simple structure. The fiber-optic transmission sensor is in the type of small dipole antenna, which uses its outside shielding layer as a pair of antennas. Design of the ...

Matrix optics is applied to a class of random, in time and space, electromagnetic pulsed beam-like (REMPB) radiation interacting with linear optical elements. A 6×6 order matrix describing transformation of a six-dimensional state vector including four spatial and two temporal positions within the field is used to derive conditions for spatio-temporal coupling. An example is included which deal...
