Pressurised Heavy Water Reactors (PHWR) play a prominent role in contributing power for the Nuclear Energy Programme in India. In 540MWe type PHWR reactors, there are horizontally placed Liquid Injection Shutdown System (LISS) tubes for injecting poison into the moderator to clamp down ... En savoir plus

Cancer causes significant human deaths. Radiofrequency ablation is an encouraging procedure for cancer treatment. The objective is to demonstrate the multiphysics simulation methodology. This paper summarizes the problem , governing equations, methodology, assumptions, simulation results ... En savoir plus

As interest in the electromagnetic spectrum expands towards the infrared and terahertz range, the distinct advantages of using semiconductors instead of metals for plasmonic applications must be understood. Plasmonic resonances in gold (Au) and indium nitride (InN) gratings are studied, ... En savoir plus

Metacomposites are new class of materials with unusual properties that can be engineered using existing materials with usual properties. The unusual properties of metacomposites are derived from the structure, analogues to atomic arrangement in crystal lattice. These material exhibits ... En savoir plus

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 ... En savoir plus

Microwave heating is an important process for many commercial, industrial and household applications. In microwave heating applications, the energy is introduced directly into the volume of the material. As a consequence the quality of the process is highly dependent on the uniformity of ...

Transition metamaterials constitute a new class of engineered materials which have material properties tailored in such a manner that the refractive index gradually changes from positive to negative. An important question is what happens at the interface of a positive and negative index ... En savoir plus

A common clinical treatment is the application of alternating electromagnetic fields using a screw implant to the weak bone tissue within the femoral head, which speed up the bone regeneration in case of avascular necrosis of the femoral head . In our present work the bipolar induction ... En savoir plus

Nanotechnology is rated as a key technology of the 21st century. In the field of nano-optics already at present, state-of-the-art scientific experiments and industrial applications exhibit nanometer to sub-nanometer design tolerances. This motivates the development and application of ... En savoir plus

Micro-grippers find applications in micro-robotics, microsurgery, micro-fluidics, micro-relays, assembling and miniature medical instrumentation. Actuation principle involved may be electrothermal, electrostatic, piezoelectric, shape memory and electromagnetic. It has been found that ... En savoir plus
