Time reversal in finite difference time domain method
IEEE Microwave and Guided Wave Letters, 1993A simple modification of Yee's FDTD algorithm allows one to reverse the time direction in FDTD simulation in much the same way as with TLM method. Numerical microwave synthesis is therefore also possible by reversing the time in the FDTD algorithm. >

The Finite-Difference Time-Domain Method
2012The finite-difference time-domain (FDTD) scheme is one of the most popular computational methods for microwave problems; it is simple to program, highly efficient, and easily adapted to deal with a variety of problems. The FDTD scheme is typically formulated on a structured Cartesian grid and it discretizes Maxwell’s equations formulated in the time ...

Stochastic finite-difference time-domain
2012This dissertation presents the derivation of an approximate method to determine the mean and the variance of electromagnetic fields in the body using the Finite-Difference Time-Domain (FDTD) method. Unlike Monte Carlo analysis, which requires repeated FDTD simulations, this method directly computes the variance of the fields at every point in space at ...

Quantum Finite-Difference Time-Domain Scheme
2020 IEEE International Conference on Computational Electromagnetics (ICCEM), 2020In quantum optics, the conventional method to quantize electromagnetic fields is canonical quantization which is analogue to the classical modal expansion method. Here, on the other hand, we show a quantum finite-difference time-domain scheme that can track the time evolution of quantum electromagnetic operators in the coordinate Hilbert space.

Broadband Finite Difference Time Domain Modeling
22nd EEGS Symposium on the Application of Geophysics to Engineering and Environmental Problems, 2009Code was designed at The Ohio State University Department of Electrical and Computer Engineering in conjunction with the School of Earth Sciences with the goal of forward modeling subsurface geological systems. To attain this goal the finite difference time domain (FDTD) method was implemented through singleand multi-processor systems leading to the ...

FPGA finite difference time domain solver for thermal simulation
International Conference on Field Programmable Logic and Applications, 2005., 2005The use of infrared (IR) images of the soil is an efficient technique to detect shallowly buried landmines. The detection is possible due to the different thermal properties of the soil and the mine. The core of this technique is the simulation of the heat transfer processes in the soil and at the soil-air interface.

Effects of Segmented Finite Difference Time Domain on GPU
2014Finite Difference Time Domain (FDTD) is the most popular method in computational electromagnetics. In acoustics, FDTD is often used as a numerical analysis technique to model mechanical wave and acoustics. FDTD in general is computationally expensive in terms of time due to its large number of time steps for accurate precision and is data parallel in ...
