We study the morphology of the chain-like aggregates formed when a external constant and uniaxial magnetic field is applied to a magneto-rheological (MR) fluid. In order to characterize the conformation of the aggregates, we study the evolution of various fractal dimensions during aggregation and disaggregation processes (i.e., when the applied field is switched on and off), using video-microsc...

A Magneto-Rheological (MR) fluid brake is a device to transmit torque by the shear force of an MR fluid. An MR rotary brake has the property that its braking torque changes quickly in response to an external magnetic field strength. In this paper, the design method of the cylindrical MR fluid brake is investigated theoretically. The mechanical part is modeled using Bingham’s equation, an approa...

We study the relation between stellar dynamo-wave propagation and structure of magnetic field. Modeling dynamo waves by well-known Parker migratory dynamo, we vary intensity drivers in order to obtain activity-wave toward Equator (as solar-activity cycle) or towards Poles. match field dynamo-active shell with that surrounding material, using a simple dissipative magneto-hydrodynamic system for ...

The temperature dependence of magneto-optical and magneto-photoconductivity measurements were carried out in the range of (200-330) K. A home made optical cryostat was used for the measurements. The measured room temperature value of the energy gap was found to be 2.211 eV. The temperature coefficient of energy gap was found to be -5.48×10-4 eV/K obtained by the optical absorption method and -4...

Until recently techniques for AI plan generation relied on highly re strictive assumptions that were almost always violated in real world environments consequently robot designers adopted reactive architectures and avoided AI plan ning techniques Some recent research e orts have focused on obviating such as sumptions by developing techniques that enable the generation and execution of plans in ...

We show that the interaction between a plasmonic and a magnetoplasmonic metallic nanodisk leads to the appearance of magneto-optical activity in the purely plasmonic disk induced by the magnetoplasmonic one. Moreover, at specific wavelengths the interaction cancels the net electromagnetic field at the magnetoplasmonic component, strongly reducing the magneto-optical activity of the whole system...

Introduction The wave propagation in magneto-electro-elastic materials has gained considerable importance since last decade. The electro-magneto-elastic materials exhibit a desirable coupling effect between electric and magnetic fields, which are useful in smart structure applications. These materials have the capacity to convert one form of energy namely, magnetic, electric and mechanical ener...

We analyze the properties of magneto-optical defect states in two-dimensional photonic crystals. With outof-plane magnetization, the magneto-optical coupling splits doubly-degenerate TE states into two counter-rotating modes at different frequencies. The strength of magneto-optical coupling strongly depends on the spatial overlap of the cavity domain structures and the cross product of the moda...

Addressing the need for passive magneto-inductive components, a lumped-element symmetric power divider has been designed and realised for a magneto-inductive cable with the resonant frequency of 95 MHz and the passband between 73 and 174 MHz. In agreement with the theory, the measured coupling loss is 6 dB for most of the passband independent of the input port. Having proved useful for magneto-...

Technological advances in sensor designs (e.g. increased sensitivity) may be achieved by combining plasmonic and magneto-optical materials, thus leading to magneto-plasmonic systems. Noble metal-ferromagnetic systems, such as Au/Co/Au trilayers and Au/FePd bilayers, are candidates for magneto-plasmonic systems, where surface plasmon polaritons (SPPs) may be modulated by externally applied magne...
