    Abstract Malignant liver tumors are the sixth most common and deadly cancer in the world and the third most common cause of cancer mortality. Hepatocellular carcinoma (primary liver cancer) is one of the most common malignancies worldwide with one of the highest mortality rates. Microwave ablation (MWA) is a new, promising, and multidisciplinary technology designed to destroy unhealthy tissue of various natures by radiating electromagnetic waves with microwave antennas. The finite element method (FEM) has been used in the present work to generate the simulated models of tapered cap floating sleeve antenna for validation of its design concepts, because FEM allows modeling of complex geometries that cannot be solved by analytical methods or finite difference models. The performances have been evaluated in terms of objective metrics, ablation zone, antenna matching, power absorption and SAR pattern.

    Abstract Self-mixed optical feedback interferometry based laser sensors show promising results in the measurement of the vibration frequency. To date several measurement methods have been developed to extract the vibration information from the self-mixed (SM) signal; however, the complexity and accuracy of the methods still need improvement. The presented work tries to fulfill the gap by realizing a novel method using maximal overlap discrete wavelet transformation (MODWT) and multi-resolution analysis (MRA). The proposed method can reconstruct the micro-harmonic (<

    Abstract The refractive index is one of the key parameters in non-invasive and label-free sensing applications. The past decade has witnessed various miniature optofluidic devices that offer several analytical functions with minuscule samples (picoliter or nanoliter) through the fusion of optics and microfluidic sciences. However, the realization of a compact, wide-range, and less-expensive refractometer is still a great challenge. In this paper, the authors have proposed a novel, to the best of our knowledge, self-mixing optical feedback interferometry (SM-OFI)-based refractometer that correlates the refractive index of a flowing liquid to the induced Doppler frequency shift. The proposed method was experimentally tested on the saline water and benzyl chloride and found close agreement with the literature results. The refractive indices of the saline water and benzyl chloride were measured to be 1.3346 and 1.54079, respectively, with a standard deviation of the order of 10

    Abstract In this article, new interstitial antenna operating at a frequency of 2.45 GHz for the treatment of hepatocellular carcinoma (HCC) using microwave ablation has been investigated. This antenna is basically an asymmetrical miniaturized choke dipole antenna with a pointed needle at the tip. A commercial finite element method (FEM) package, COMSOL Multiphysics 3.4a, has been used to simulate the performance of needle tip choke antenna. The performance of the antenna has been evaluated numerically, taking into account the specific absorption rate, antenna impedance matching and geometry of the obtained thermal lesion, and the temperature distribution plot obtained shows that maximum temperature was attained in this simulation. The antenna is also capable of creating a spherical-shaped ablation zone. The size and shape of the ablation zone can be slightly adjusted by adjusting the choke position in order to maintain spherical ablation zones.
