In the past few years, metamaterial perfect absorbers (MPA) have been extensively studied due to their incredible ability to manipulate electromagnetic waves and provide a broadband, polarization-independent, and wide-angle response for a host of applications. The need for high ... Per saperne di più
In Mexico there is a decline in the production of oil deposits due to the lack of effective treatment of oil emulsions, which generate a problem in the reinjection of emulsified water, transport of oil with high water content and corrosion in the oil refineries. Through the simulation ... Per saperne di più
Field-emitter (FE) electron sources offer significant advantages over photocathode and thermionic sources due to their ability to be operated without the need for an auxiliary laser system or a heating source. While FE cathodes have been traditionally used in DC environments, we explore ... Per saperne di più
Composite systems are becoming more and more widespread across industries and the capability to finding and tracking internal defects before they have grown to major deterioration is of paramount importance in regard to safety, economy and maintenance. We are exploring a novel method of ... Per saperne di più
In a magnetic resonance imaging (MRI) system, it is necessary to excite the nuclei of a patient into coherent precession for imaging. This requires a coupling between the nuclei and a source of radio frequency (RF) power using a transmitter. To receive a meaningful signal, we also need ... Per saperne di più
Recently, the researchers usually use the hydrodynamic Drude model (HDM)to investigate the nonlocal optical response of metallic nanostructure. The advantage of the HDM is easy to implement numerical calculation for larger and more complex shaped nanoplasmonic structures. For the HDM, it ... Per saperne di più
Microwave heating is known for its efficiency and instantaneity. However, the non-uniformity of the microwave heating has limited the development of its application in industry. In order to solve this problem, a metal patch sticking to the turntable was proposed. During the heating ... Per saperne di più
A patch antenna based on metamaterials of composite split-ring-resonators (CSRRs) and strip gaps is designed with COMSOL Multiphysics® software. The antenna is constructed by using CSRR structures in forms of circular rings on the patch and employing strip gaps on the ground plane. The ... Per saperne di più
Metamaterial-based absorbers play a significant role in applications ranging from energy harvesting and thermal emitters to sensors and imaging devices. The middle dielectric layer of conventional metamaterial absorbers has always been solid. Researchers could not detect the near field ... Per saperne di più
Surface-enhanced Raman scattering (SERS) is a fingerprint spectroscopy whose sensitivity is down to single molecule level. The mechanism of SERS is mainly contributed to huge enhancement of local electric field, which originated from surface plasmon resonance of metal nanostructures. It ... Per saperne di più
