In recent years, optical manipulation using optical radiation pressure has been widely studied. In this study, the radiation pressure exerted on various kinds of microscopic objects with different laser beams was evaluated by COMSOL Multiphysics software. By changing beam shapes, microscopic objects can be trapped and rotated. This paper is in Japanese.

The accurate estimate of values of electromagnetic parameters are essential to determine the final circuit speeds and functionality for designing of high-performance integrated circuits and integrated circuits packaging. In this paper, a new quasi-TEM capacitance and inductance analysis of multiconductor multilayer interconnects is successfully demonstrated using the finite element method (FEM) ...

In this section, we design an invisible cloak using the composite medium of silver nanowires with elliptical cross-sections embedded in a polymethyl methacrylate host. Under the guidance of an analytical effective medium approach, we use the parameter retrieval method to design a well-performed invisible cloak, based on an empirical revised version of the reduced cloak. The cloak is numerically ...

Since the invention of laser sources, understanding the interaction between the laser and biological tissues is a subject of great importance because of their medical applications in particular for diagnostic purposes. They recently found a growing interest in the sector of the arboriculture to check the fruits quality in a non-destructive way. In this work, we study the interaction between the ...

Low-dimensional semiconductor nanostructures, in which charge carriers are confined in a number of spatial dimensions, are the focus of much solid-state physics research, offering superior optical and electronic properties over their bulk counterparts. Both two-dimensional (2D) and zero-dimensional (0D) structures have seen wide-ranging applications in laser diodes, solar cells and LEDs to name ...

We present in this paper a model to study new memory devices with embedded nanocrystals, emerging in microelectronics. The theoretical calculations and their implementation in FEMLAB are detailed, leading to a quite simple and realistic model. One key point for these memories is the electronic tunnel transfer to store the charge into a nanocrystal. This is why we carry out a brief analysis of ...

This paper showed that: * SAG-MOCVD is a powerful tool to fabricate OEICs and is also effective to extract true surface kinetics during MOCVD. * GaAs-MOCVD process was examined by SAG analysis where it was seen that below 600ºC, surface kinetics shows non-linear behavior. * Surface reaction rate constant of adsorbed species was constant against offset angle, while adsorption equilibrium ...

Ultrafast lasers are widely applied in micromachining, material science and physics. In industry, picosecond lasers are becoming more and more established. For pulse lengths shorter than the electron-phonon coupling time, heat affected zones are negligible. Thermally sensitive materials can be processed using ultrashort pulse laser radiation. Multi-component materials and poorly absorbing ...

Ion implantation in insulating materials leads to local variations in mechanical and optical properties that can be exploited for the fabrication of micro-structures. In particular, ion irradiation of diamond causes the formation of buried amorphised layers, with correspondent mass density and refractive index variations that depend on the level of “damage” of the crystal structure. ...

Mit Hilfe des Softwareprogramms COMSOL zur Modellierung physikalischer Vorgänge wurden die Polarisationseigenschaften einer mikrostrukturierten Singlemodefaser untersucht. Ausgangspunkt der Simulationen waren experimentelle Untersuchungen, nach denen diese Faser eine ungewöhnlich starke Doppelbrechung aufwies. Die Doppelbrechung der Faser und damit ihre Fähigkeit zur Polarisationserhaltung ...
