Semiconductor materials such as gallium arsenide are attractive for nonlinear optical applications because they have a fundamental bandgap in the region of the optical part of the electromagnetic spectrum, so that near-resonant excitation can be achieved, resulting in high nonlinear responses; in ...
This gives rise to the emission of a series of fully coherent harmonics, only odd orders, spanning a wide range of the electromagnetic spectrum from the near Ultra-Violet (UV) to the soft X-rays. Two major electrons trajectories, called the short and the long ones, contribute to the ...
The electromagnetic spectrum emitted by a one-dimensional atom driven by a strong laser field is obtained by use of the acceleration form and interpreted by means of few general properties of the matrix elements of the acceleration operator. We show that the emission occurs essentially in a ...
Electromagnetic finite element analysisPhysics- aware neural networkHierarchical variational autoencoderDeep learningFinite element (FE) analysis is one of the most accurate methods for predicting electromagnetic field scatter; however, it presents a significant computational overhead. In this study, we ...
To determine the correct order of increasing frequency of electromagnetic radiations, we need to understand the electromagnetic spectrum and the relative frequencies of different types of radiation. The electromagnetic spectrum is typically arranged from the lowest frequency to the highest frequency as foll...
High-order diffraction (HOD) from optical microstructures is undesirable in many applications because of the accompanying ghosting patterns and loss of efficiency. In contrast to suppressing HOD with subwavelength structures that challenge the fabricatio
Among textile materials there is a group of smart/intelligent textiles that are sensitive to external stimuli such as stress, temperature, humidity, the intensity of the electromagnetic field or the presence of chemical substances. Under the influence of the above-mentioned external factors, the ...
