Radio Frequency MEMS devices have emerged to overcome the problem of high losses associated with semiconductors at high frequencies. A tunable MEMS capacitor is a micrometre-scale electronic device whose capacitance is controlled through different actuation mechanisms which govern the ... 詳細を見る
High-power couplers working at 350 MHz for particle accelerator cavities are presently under development in the LEHIPA project at BARC. It is important to analyze RF losses on conducting surfaces and resulting thermal profiles. COMSOL Multiphysics® is used to study these coupled RF ... 詳細を見る
Metamaterial [1, 2] is an artificially structured material where it’s electrical (ϵ), magnetic (μ) and its refraction properties (n) are simultaneously negative in narrow frequency band. Currently, metamaterials are being widely used in microwave and radio frequencies as devices [3, 4] ... 詳細を見る
The variability of the design parameters caused by material properties like thermal conductivity is the major challenge in Micro Electromechanical System (MEMS). In resonator design the basic problem is that the frequency changes with temperature variation and quantitative explanation ... 詳細を見る
Dye sensitized solar cells (DSSCs) have received tremendous attention as alternative photon harvesting devices. While the sintered TiO2 nanoparticle network attached with dye molecules achieves efficient photon absorption, the electrons have to diffuse through the long TiO2 network to ... 詳細を見る
Partial differential equations (PDEs) govern many phenomena in nature. Solving optimization problems which comprises the solution of large number of PDEs, is expensive concerning time and memory. Therefore, to reduce the solution cost, original problem is transformed to a corresponding ... 詳細を見る
Intracerebral hemorrhage is a condition where a blood vessel in the brain ruptures and causes internal bleeding leading to hemorrhagic stroke. 800 in every 100,000 people suffer from stroke each year and it's one of the major causes of mortality worldwide. Diagnosis involves Neurological ... 詳細を見る
In high-speed digital design, strong electromagnetic coupling exists between adjacent transmission lines. This manifests itself in the form of crosstalk voltage induced on either line. Crosstalk is modeled in terms of capacitance and inductance matrices which are extracted using COMSOL ... 詳細を見る
The Micro electro mechanical systems (MEMS) technology provides us a platform to interface between mechanical and electrical components. In this paper, we have designed MEMS accelerometer based on piezoelectric property, and simulated using COMSOL Multiphysics®. The design, which has ... 詳細を見る
In this contribution we study how a planar photonic crystal waveguide (PhCW), created by introducing a line defect in the photonic crystal, can modify the projected local density of states (LDOS) for a dipole emitter. We use the COMSOL Multiphysics® RF Module to carry out eigenvalue ... 詳細を見る
