In this paper will be presented how an electronic system and its components will respond in case of an impact of an external electromagnetic pulse (EMP). In the first instance the coupling process of transient electromagnetic pulses into electronic systems will be shown. Out of that the disturbing signal inside the system, which is necessary for the following simulation, will be described ...

Microwave imaging has been recently proposed as a potentially useful screening technique for breast cancer. This method detects abnormalities in the tissue based on permittivity difference between breast normal and malignant tissue. In this method breast is illuminated by high frequency electromagnetic wave, and received waves are then analyzed in order to construct a map of breast\'s ...

By introducing a periodic modulation in a waveguide, it is possible to create an interaction between forward-traveling and backward-traveling modes of an optical waveguide. Bragg grating may be a one dimensional diffraction grating which diffracts light from the forward-traveling mode into the backward traveling mode. Since the Bragg grating reflects at the wavelength for which it is ...

Use of the terahertz(THz) region, which is unexplored frequency band, is investigated and expected for the next-generation high-speed wireless communication. In this presentation, we propose a monolithic integrated device by using mesa-shaped compound semiconductor and a thin-metal broadband antenna which is capable in THz operation, and we analyze several characteristics of the device by using ...

Influence of chiral objects on spontaneous emission of atoms and molecules is under attention nowadays. The problem of interaction of chiral molecules with one  or two chiral  spheres was solved analytically recently by our group. The analytical results however are very difficult and needed to be calculated carefully. We modify the RF Module of COMSOL Multiphysics® in order to simulate ...

We report here on the use of the COMSOL emw (electromagnetic waves) module in the design of a microwave launcher. This launcher is to be used in a microwave Doppler sensor that is incorporated into a chemical looping combustion system. The launcher is designed in two steps. First, we determine the best mode for launching a wave into air from an overmoded cylindrical waveguide. he TE11 mode is ...

Heterogeneous materials with different phases, are conductive and insulating (dielectric), and are physically present in different natural materials as e.g. atmospheric ice. Jonscher’s proposed ‘universal dielectric response’ is not sufficient for such materials, as it only reflects conductivity as a nonlinear function of frequency, whereas at lower temperatures dipolar vibrations are also very ...

INTRODUCTION: Researchers in the biomedical field have recently become interested in the potential applications of plasomics. Surface plasmon resonance based on optical properties of metallic nanostructures can be used for detection of special biological targets. Gold nanostructures with different shapes and sizes have been designed to achieve high enhancement factor (EF), wide range of ...
