Nonlinear magnetization dynamics is essential for the operation of numerous spintronic devices ranging from magnetic memory to spin torque microwave generators. Examples are microwave-assisted switching of magnetic structures and the generation of spin currents at low bias fields by high-amplitude ferromagnetic resonance. Here we use X-ray magnetic circular dichroism to determine the number den...

The measurement of microwave radiation has been widely used in atmospheric remote sensing, such as temperature profiling, and vapor and liquid column measurements [1] [5]. The radiation from atmosphere is due to the absorption (emission) and scattering of electromagnetic (EM) wave by atmospheric particles (gaseous molecules, liquid water droplets and ice crystals). The absorption directly contr...

In a recent experiment the microwave emissivity of foam on calm water was measured to be 0.75 to 0.95 and dependent on polarization [1]. Microwave radiometric measurements of breaking waves on the open ocean showed that the emission due to wave breaking varies with the time dynamics of the wave, as well as with radiometer polarization and viewing angle [2]. However, the inherent intermittency a...

Microwave heating–drying of wood using a wave guide is a relatively new area of research. In order to gain insight into the phenomena that occur within the wave guide together with the temperature distribution in the wood, a detailed knowledge of absorbed power distribution is necessary. In this paper, a two dimensional numerical model is developed to predicted the distribution of electromagnet...

An inherent element of research and applications in photonics is a beam of light. In magnonics, which is the magnetic counterpart of photonics, where spin waves are used instead of electromagnetic waves to transmit and process information, the lack of a beam source limits exploration. Here, we present an approach enabling generation of narrow spin wave beams in thin homogeneous nanosized ferrom...

[1] Microwave and acoustic systems operated in the large wind-wave tank in Luminy, Marseille, France, show that most small-scale waves produced at large angles to the wind are products of breaking events bound to longer waves in the tank. These longer waves propagate at the dominant wave phase speed for fetches near 7 m but travel at speeds corresponding to the phase speed of a wave half as lon...

In this paper, an efficient wave concept iterative process (WCIP) with auxiliary Sources is presented for full wave investigation of an active microwave structure on micro strip technology. Good agreement between the experimental and simulation results is observed. Keywords—WCIP, Dual-Gate Transistor, Auxiliary source.

Near-field ranges operate by measuring the electromagnetic field near the antenna and then mathematically transforming the data to any arbitrary location. Near-field operations are a form of microwave holography. The wave front measurements are normally made on a planar, spherical or cylindrical surface. This paper discusses primarily the planar configurations as used in the measurement of larg...

This paper describes the applicability of subcarrier multiplexing to light wave multiple-access networks. It is shown how currently available microwave and light wave components can be used, by using subcarrier multiplexing, to provide high-capacity networks and also how can increase the number of users who support the network.

In this paper, a travelling wave electroabsorption modulators (TWEAMs) based on asymmetric intra-stepbarrier coupled double strained quantum wells (AICD-SQW) active layer is designed and analyzed at 1.55 μm for the first time. The AICD-SQW structure has advantages such as very low insertion loss, zero chirp, large Stark shift and high extinction ratio in comparison with the intra-step quantum w...
