Hyperthermia is newly back in the interest of both, clinical and research oncologists, because of its properties to directly produce permanent damages of the treated tumors and to elicit important immunological responses against cancer cells by changing their immunogenicity. Microwave ablation is used in the treatment of primary and secondary tumors of the liver. Microwave antennas ...

Curved cone corrugated ground plane conical antenna has been designed and analyzed using Finite Element Method. In this paper, we introduce a novel Curved cone corrugated ground plane conical antenna for ultra-wideband (UWB) applications. The antenna is composed of curved cone with narrow corrugation on finite ground plane and fed by a 50? coaxial cable. The designed antenna operates over ...

For the purpose of accurate and efficient design of a microwave structure, sophisticated optimization techniques are typically used. The optimization process can greatly benefit from the availability not only of the objective function, but also its gradient. Numerical electromagnetic solvers do not provide the gradient information, thus defaulting to the finite-difference approximation at the ...

The purpose of this work was to establish a reliable radio frequency (RF) heating simulation which directly provides transient temperatures for medical devices with high geometric fidelity. These temporal results of localized temperatures can be used to determine conditions for safety of medical devices in the magnetic resonance (MR) environment. Information from this work will directly benefit ...

A computer controlled microwave exposure system and specialized applicators were constructed for the purpose of facilitating accurate observations of microwave radiation effects on uninfected and infected biological tissue in vitro and in vivo under different electromagnetic modalities and exposure configuration. To address diverse requirements, three different applicators were developed: a ...

In a solid core PCF, structural parameters and the number of rings in the cladding region decide confinement losses, dispersion coefficients as well as bending losses. This paper evaluates some of commercially available solid core photonic crystal fibers. The dispersion coefficients and sensitivity of these fibers are estimated using COMSOL Multiphysics®, and compared with the theoretical values ...

Chiral SPPs can be generated by linearly polarized light incident at the end of a nanowire, exciting a coherent superposition of three specific nanowire waveguide modes. Chirality is preserved in the emitted photons, creating a subwavelength ¼ wave plate.

We present a Finite Element Method (FEM) to calculate the complex valued k(?) dispersion curves of a photonic crystal slab in presence of both dispersive and lossy materials. In particular the method can be exploited to study plasmonic crystal slabs. We adopt Perfectly Matched Layers (PMLs) in order to truncate the open boundaries of the model, including their related anisotropic permittivity and ...

Upon operation, the magnetron of a conventional microwave oven induces a pattern of standing electromagnetic waves in the oven cavity. Interactions with the field define the amount of energy absorbed in a part of a food object within the cavity. The well-known inhomogeneous heating produced in a microwave oven is partially an effect of the standing waves’ natural nodes and antinodes and ...

Design of Microwave Resonance Cavity (MRC) to generate non-thermal plasma to treat NOx and SOx from marine diesel engine is presented in this paper. Microwave frequency of 2.45GHz is used generate the required plasma. A number of wave guides are used to transfer the microwave energy into to MRC from the microwave source. COMSOL multi-physics software is used to model the waveguides and to ...
