Nanophotonics or nano-optics is the study of the behavior of light on the nanometer scale, and of the interaction of nanometer-scale objects with light. It is a branch of optics, optical engineering, electrical engineering, and nanotechnology. It often involves dielectric structures such as nanoantennas, or metallic components, which can transport and focus light via surface plasmon polaritons.

기초지식 STFT(Short Time Fourier Transform) 강인득 연구원 STFT는 FFT와 더불어 소음진동 분석에 기본이자 필수인 신호처리 기법입니다. 그럼 STFT에 대해 알아보도록 하겠습니다. 이름에서 살펴보면 Short Time이라는 단어가 들어갑니다. 뒤에 나오는 Fourier Transform은 여러분도 잘 아시는 푸리에 변환입니다.

Geometry nodes has been extended with large performance improvements, more possibilities with many new mesh nodes, and various other utilities and features. In bold you can find the names of 19 newly added nodes. The Set Position node has been optimized for meshes, with up to a 4x improvement for a simple field (602ecbdf9a).

회절(回折, Diffraction)은 대표적인 파동 현상 중의 하나이다. 순우리말로 ' 에돌이'라고 하며 음파나 전파 또는 광파 등이 장애물이나 좁은 틈을 통과할 때, 파동이 그 뒤편(그림자 부분)까지 전파하는 현상이다. 간섭현상으로서의 회절 현상으로는 가시광이 회절격자에 의해 반사되는 경우, 엑스선 이 고체 결정에 의해 반사되는 경우, 파장이 좁은 틈을 지날때 생기는 1~2차 회절 현상 등이 있다.

Wave optics also called Physical optics deals with the study of various phenomena such as polarization, diffraction, interference and other occurrences where ray approximation of geometric optics cannot be done. Thus, the section of optics that deals with the behavior of light and its wave characteristics is said to be wave optics.

The Raycast node intersects rays from one geometry onto another. The source geometry is defined by the context of the node that the Raycast node is connected to. Each ray computes hit points on the target mesh and outputs normals, distances and any surface attribute specified.

An electromagnetic pulse ( EMP), also a transient electromagnetic disturbance ( TED), is a brief burst of electromagnetic energy. Depending upon the source, the origin of an EMP can be natural or artificial, and can occur as an electromagnetic field, as an electric field, as a magnetic field, or as a conducted electric current.

The Finite-Difference Time-Domain (FDTD) method is a rigorous and powerful tool for modeling nano-scale optical devices. FDTD solves Maxwell's equations directly without any physical approximation, and the maximum problem size is limited only by the extent of the computing power available.

The Finite-Difference Time-Domain (FDTD) method[ 1,2,3] is a state-of-the-art method for solving Maxwell's equations in complex geometries. Being a direct time and space solution, it offers the user a unique insight into all types of problems in electromagnetics and photonics.
