“…Using this type of resist in association with silica beads, we successfully obtained pillars at a nanometer scale. To deposit the layer of silica beads on a sol–gel film, we used a Langmuir–Blodgett method owing to the relative simplicity with which the conditions of self-assembly can be achieved and the accurate control of the deposition process achieved even over large areas. − The simulations using the rigorous method RCWA (Rigorous Coupled Wave Analysis) confirm well-known phenomena of focusing the light through the silica particles with formation of a photonic nanojet, which propagates into the background medium from the shadow-side surface of a plane-wave illuminated dielectric microsphere …”

The authors demonstrate a unique low cost process to print 2D, submicron size, and high refractive index nanopillars using a direct colloidal-photolithography process. A well collimated i-line source emitting at 365 nm wavelength illuminates a mono layer of silica microspheres of 1 μm diameter deposited on a photosensitive TiO2-based sol-gel layer. No etching process is needed since this layer is directly UV photo patternable like a negative photoresist. Furthermore, this thin layer offers interesting optical properties (high refractive index and optical transparency) and good mechanical and chemical stability and thus can be directly used as a functional microstructure (for PV or sensor applications, for example). The paper describes the modeling of the electric field distribution below the spheres during the illumination process, the photochemistry of the TiO2 sol-gel layer process, and preliminary results of TiO2 nanopillars of around 200 nm in diameter fabricated on a three-inch substrate.

A brief theory and simulation overview for the purpose of design is presented with examples applies to modeling the physical properties, behavior, and phenomena of nanomaterial. This review paper constructs perspectives that consider coupling traditional domains of simulation by novel pathways to produce accurate representations of nanomaterial properties, behavior and phenomena. It is all about size scaling and how different approaches are able to simulate, integrate or simply pass the baton to the next level of complexity. In macroscopic world, the atomic or molecular information alone may not be directly useful. Nor is the bulk information useful in the microscopic world without intimate knowledge of molecular makeup. Therefore, when designing Nanomaterials, knowledge of properties spanning the complete range of size is the prerequisite of a recommended self-consistent approach. In fact, regarding applications in both industry and academia, the simulation first approach often can lead to great savings in time. This review paper focuses mostly on optical and electronic properties but a section is added that provides a segue into mechanical properties for future consideration.

“…The convergence rate is greatly improved by rearranging Maxwell's curl equations [ 9 ] . The computational efficiency of FMM is improved by introducing the form of auxiliary equations [ 10 ] . In our previous works, efficient FMM methods for binary gratings [ 11 ] and ultrathin one‐dimensional periodic structures [ 12,13 ] were proposed.…”

The solution of large matrix eigenvalues and complex linear equations limits the Fourier modal method (FMM) application in ultrathin metallic gratings (UMG) analysis. This paper proposes an efficient and explicit FMM method for analyzing UMG. The proposed method avoids solving complex linear equations and eigenvalues of eigenmatrix in the conventional method by simplifying the implementation equations. Two numerical examples then verify the reliability of the proposed method compared with CST simulations and the conventional method. The proposed method is proven efficient in decreasing the CPU time by over 80% and demanding significantly less memory.
