Abstract Spin-based technologies can operate at terahertz frequencies but require manipulation techniques that work ultrafast timescales to become practical. For instance, devices based on spin waves, also known as magnons, efficient generation of high-energy exchange waves nanometre wavelengths. To achieve this, a substantial coupling is needed between the magnon modes and an electro-magnetic ...

Electromagnetic waves propagating in air are visually observed with phase evolution in real time by live electro-optic imaging technique. We show how geometrical and crystallographic arrangements of an electro-optic sensor plate enable the realization of the real-time visual observation of traveling 100-GHz electromagnetic waves. For this purpose, a generation technique for a 100-GHz optical lo...

Wave scattering analysis implemented by boundary element methods (BEM) and the normal mode expansion technique is used to study the sizing potential of two-dimensional shaped defects in a wave guide. Surface breaking halfelliptical shaped defects of three opening lengths (0.3, 6.35 and 12.7 mm) and through-wall depths of 10–90% on a 10 mm thick steel plate were considered. The reflection and tr...

In this paper, electro-magnetic design and thermal analysis of wheel hub motors, incorporated into the hub of a wheel and driven it directly, of electric vehicles were performed by using analytical and CFD methods. Since thermal management impacts the continuous power capability of electric machines, thermal analysis coupled electro-magnetic analysis are needed to reduce size and improve its pe...

Introduction: The use of cell phones is widespread and there are public concerns regarding its possible deleterious effects on human health especially on the pregnancy outcomes. In this study, structural changes of the placenta after applying the cell phone radiation were examined in the mice model.   Materials and methods: For this work, 40 pregnant Balb/C mice were randomly allocated to ...

The purpose of this work is to implement panorama stitching from a sequence of photos taken by cell phone camera on the Android phone system. The photos for panorama stitching are captured in a fixed linear spatial interval based on magnetic compass provided by Android cell phone. The computation is carried out either on phone or by a cloud according to the number of photos used for the panoram...

Magneto-electro-elastic materials are multiphase smart materials that exhibit coupling among electrical, magnetic and mechanical energy fields. Due to this ability, they have been the topic of numerous research in the past decade. In this paper, buckling behavior of a multiphase magneto-electro-elastic rectangular plate with simply supported boundary conditions is investigated, based on Reddy’s...

Magnetic field detection of biological electric activities would provide a non-invasive and aseptic estimate of the functional state of cellular organization, namely a syncytium constructed with cell-to-cell electric coupling. In this study, we investigated the properties of biomagnetic waves which occur spontaneously in gut musculature as a typical functional syncytium, by applying an amorphou...
