in this paper, shielding effectiveness (se) of a perforated enclosure with imperfectly conducting walls is evaluated. to this end, first, an accurate numerical technique based on method of moments (mom) ispresented. in this method, lossy metallic walls of the enclosure are replaced by equivalent electric surfacecurrent sources. then, the impedance boundary condition on the imperfectly conductin...

We demonstrate electrorotation of metal nanowires phase-locked to a driving alternating current electric field. Field rotation was accomplished by a low-frequency signal that modulates the amplitude of the high-frequency field. Steady, synchronous rotation of the nanowires was observed for frequencies up to a maximum rotational frequency, which depends on the magnitude of the applied electric f...

Using an Electric Differential (ED) in electric vehicle has many advantages such as flexibility and direct torque control of the wheels during cornering and risky maneuvers. Despite its reported successes and advantages, the ED has several problems limits its applicability, for instance, an increment of control loops and an increase of computational effort. In this paper, an electric differenti...

Electric field induced by charge oscillation has been investigated by simulation of the electric field distribution using the finite-difference frequency-domain method. In addition, the electric field was induced by spatial oscillation of a sample to which a DC voltage was applied. The simulation and evaluation of the electric field verified that the efficiency for inducing the electric field h...

This paper presents a multi-agent based dynamic stability control of electric power systems especially for low-frequency global mode of oscillations. Different types of intelligent agents are also proposed to realize the proposed wide area stability control system: monitoring agents for gathering required information to evaluate the dynamic stability of the study system, control agents which pe...

Animals rely on sensory information for the control of their behavior. Understanding this process requires a detailed description of the sensory feedback that they receive, which is often determined by an animal's proximity to conspecifics and its own movement within the environment. This dissertation examines the role of social behavior and movement for the modulation of electrosensory feedbac...

Efficient frequency conversion techniques are crucial to the development of plasmonic metasurfaces for information processing and signal modulation. In principle, nanoscale electric-field confinement in nonlinear materials enables higher harmonic conversion efficiencies per unit volume than those attainable in bulk materials. Here we demonstrate efficient second-harmonic generation (SHG) in a s...

In this paper a Fuzzy Logic based load frequency control system (LFC) with Superconductor Magnetic Energy Storage System (SMES) in a multi area electric power system was explained. If a large power imbalance is suddenly happened in a multi area power electric system, generation units and also consumer sides will be affected by the distortion in the energy balance between both two sides. This im...

Load frequency control forms an essential component of Automatic Generation Control, which helps to maintain the power system frequency constant while maintaining the tie-line power flow with neighbouring áreas at scheduled values for an interconnected power system. With deregulation, the structure of electric power industry is changed thoroughly with multiple bilateral transactions taking plac...
