I made geometry as always in scattering formulation (solving for scE), all air and PML, and have launched plane wave with amplitude 1 V/m. 과거에 비해 상대적으로 저렴한 가격에 활용해 볼 수 있고 (물론 학교의 경우에), ui도 많이 향상되어서 gui를 통한 작업이 수월하게 이루어질 수 있게 해 준다. Design and set up the Femtosecond laser direct writing system and nonlinear optical metrology system. We numerically investigated the optimal thickness of TiO2 over-layer in the proposed sensor and compared its performance to that based on typical bimetallic layers of silver-and-gold in the aqueous media using finite-difference time domain approach.

El método FDTD ha demostrado ser el enfoque más eficaz y proporciona resultados exactos de la penetración del campo en los tejidos biológicos. ldev and graphene_electro-optic_modulator_2. This is a widely used technique in which space is divided into a discrete grid and the fields are evolved in time using discrete time steps — as the grid and the time steps are made finer and finer, this becomes a closer and closer approximation for the true continuous equations, and one can.
