This paper describes the Virtual Prototyping based on a COMSOL Multiphysics® simulation for a novel Microwave Fin Taper (FT) Spatial Power Combiner (SPC) Amplifier. The analyzed system is waveguide (WG) based, and uses FT Probes to convert the energy of a rectangular WG EM fundamental mode to a Microstrip Transmission Line TEM mode, in order to be amplified by a Solid State Power ...

Non-communicable diseases (NCDs) have globally become a prevalent problem, accounting for more than 60% of the mortality worldwide. NCDs impose socioeconomic consequences to low-income countries as 80% of NCD deaths occur in such countries [1, 2]. The World Health Organization has necessitated that cost-effective preventive measures, which have an immediate impact on the burden at population ...

The measurement of dielectric constant at frequencies of 20 GHz or greater is important for specifying the optical properties of materials at millimeter wavelength. One method of measurement uses a resonant cavity containing a sample of the material, and relates the resonant frequency and quality factor of the resonance to the complex dielectric constant through electromagnetic simulation. ...

Phase gratings are used in many applications owing to their high transmission and thus higher diffraction efficiencies. COMSOL is based on finite element modeling and is chosen for 2 reasons; firstly, because it can handle complex 2-D and 3-D geometries and secondly, it can handle the vector nature of these structures. The objective of the design is to compare the results of a commonly used ...

We are developing a reflective metal-insulator-metal (MIM) filter with narrow band absorption. In the MIM structure, the interaction between subwavelength multilayer and visible light, and the resultant surface plasmon resonance (SPR) in specific illumination conditions must be understood. Such electromagnetic field interactions have been analysed using COMSOL Multiphysics and RF Module.

In this project a two dimensional second order nodal and linear edge elements programming model for homogeneous waveguide is developed and simulated in MATLAB® software Environment. The objective is to reduce or eliminate spurious solutions and to cater for any arbitrarily shaped waveguides using triangular edge elements. The formulation is developed using the E-Field and to make use of the ...

Wireless sensor network has been extensively applied in a wide variety of areas such as defense, agriculture, transportation, etc. The major challenge in those networks is the finite energy of the sensor node which is by and large engaged in transmitting and receiving data. It is known that substantial amount of energy is consumed in transmitter portion. The constituent unit of the transmitter i ...

Detecting light emitted by fluorescent molecules with resolution down to single photon is an important problem in various fields of sciences and applications, such as solid-state physics, quantum information processing and medicine. The detection probability can be improved via enhancement of excitation and emission. Enhancement both of these processes can be reached by localized surface plasmon ...

Liquid-crystal elastomers (LCEs)  have attracted a great attention in recent years due to their high potential in a wide range of applications, from microfluidics components  to artificial muscles . The photo-mechanical response of LCEs is due to their constitutive photo-sensitive molecules, which change shape when absorbing part of the incident light. These microscopic deformations can ...
