Electromagnetic simulations of nanooptics based on the Finite Difference Time Domain (FDTD) method.
Written in English
Electrodynamic simulations based on the Finite Difference Time Domain (FDTD) method were used to investigate the transmission properties of periodic nanohole arrays in opaque metal films surrounded by dielectric media. It is believed that the mechanism for extraordinary transmission through these nanoarrays involves the coupling of evanescent Surface Plasmon Polariton (SPP) fields to the momentum of the array. Theoretical calculations performed show that transmission peak positions depend on the periodicity (separation) of the holes and changes in the surrounding dielectric environment. Additionally, polarization effects, unconventional aperture shapes and interactions between localized surface plasmons of individual apertures were analyzed. The combination of surface plasmon generated fields, their sensitivity to contacting dielectric medium, and the tunable properties of these periodic arrays provides insight into the potential design of novel chemical biosensors.

Electromagnetic modeling is essential to the design and modeling of antenna, radar, satellite, medical imaging, and other applications. In this book, author Levent Sevgi explains techniques for solving real-time complex physical problems using MATLAB-based short scripts and comprehensive virtual tools. Electromagnetic field distributions come from Maxwell's equations, and analytical solutions are the first step as a first-hand approach. Complete numerical simulations, such as the finite-difference time-domain (FDTD) and finite-element (FE) methods, would require an enormous amount of memory and computational speed.
This book introduces the powerful Finite-Difference Time-Domain method to students and interested researchers and readers.

The finite-element method (FEM) is a numerical method for solving partial differential equations (PDEs). In the field of nano-optical devices, finite-element methods are mainly used for simulations of optical effects and optical device properties.
The relevant models in. Our method is based on a mixed finite element method using edge elements with different types of meshes in different regions. Numerical results demonstrate that our algorithm is quite effective for simulating cloaks in time-domain. To our knowledge, this is the first cloak simulation carried out by the time-domain finite element method.
Induced-polarization (IP) effects have a significant influence on transient electromagnetic (TEM) data, which commonly manifest a reversed sign. Polarization media usually have a very high economic value. To study the IP effects, a new method for modeling the time-domain electromagnetic signals of 3D dispersive materials is developed.
