Finite-difference time-domain method
Finite-difference time-domain or Yee's method (named after the Chinese American applied mathematician Kane S. Yee, born 1934) is a numerical analysis technique used for modeling computational electrodynamics (finding approximate solutions to the associated system of differential equations). Since it is a time-domain method, FDTD solutions can cover a wide frequency range with a single simulation run, and treat nonlinear material properties in a natural way.
The FDTD method belongs in the general class of grid-based differential numerical modeling methods (finite difference methods). The time-dependent Maxwell's equations (in partial differential form) are discretized using central-difference approximations to the space and time partial derivatives. The resulting finite-difference equations are solved in either software or hardware in a leapfrog manner: the electric field vector components in a volume of space are solved at a given instant in time; then the magnetic field vector components in the same spatial volume are solved at the next instant in time; and the process is repeated over and over again until the desired transient or steady-state electromagnetic field behavior is fully evolved.

Implementing FDTD Equations with Matlab in one Hour
In this video, I am implementing a finite difference time domain solver (FDTD) in one hour using Matlab. 0:00 I will start gently with 1D propagation, results are seen at 10:00. 10:50 I add periodic boundary conditions. Results are seen 13:00. 13:30 Discussion about temporal offset between E and B. Splitting propagator so that they are on equal time. Results are seen 15:05. 16:10 Discussing observed dispersion in FDTD simulation. I Fourier transform the finite difference propagator operator from (r,t) space to (k,omega)-space, and we observe a particle with negative mass, which results from errors in fd-stencil. Final result: 19.14 . 20:40 Theory of adding polarizable material. 22:20 Implementing polarizable material. (I get slightly confused about sign of P. In zero frequency, P shoul...

Finite-difference time-domain method
Finite-difference time-domain or Yee's method (named after the Chinese American applied mathematician Kane S. Yee, born 1934) is a numerical analysis technique used for modeling computational electrodynamics (finding approximate solutions to the associated system of differential equations). Since it is a time-domain method, FDTD solutions can cover a wide frequency range with a single simulation run, and treat nonlinear material properties in a natural way.
The FDTD method belongs in the general class of grid-based differential numerical modeling methods (finite difference methods). The time-dependent Maxwell's equations (in partial differential form) are discretized using central-difference approximations to the space and time partial derivatives. The resulting finite-difference equations are solved in either software or hardware in a leapfrog manner: the electric field vector components in a volume of space are solved at a given instant in time; then the magnetic field vector components in the same spatial volume are solved at the next instant in time; and the process is repeated over and over again until the desired transient or steady-state electromagnetic field behavior is fully evolved.

Solar Lights
by: FadeoutNeed to gather all the pieces and to center my thoughts
Visualize you close to me
Cos you know baby I can't see you through a dark night
Such a fine line that you walk
Rain keeps pouring acid on my skin
And my soul turns into metal
She has turned this bed into a tomb
And brought death right through to me
I have stayed in your solar lights
Stayed so long that I'm too blind
Way too blind to see myself
Way too weak that I could tell
I have never felt a rain like this before
Never thought that I could drown in you
Stayed too long in your solar lights
Such a beautiful shade in a beautiful lie
All the city lights and answers in the halos they form
Such a sad sad sight to see
I have seen her in a portrait of a dark light
Such a fine line that she walks
I have shattered pages but remembered
Thanks to her I'm made of metal
She has took this soul for a ride
But it's way too late for me
Drops of pain rain down
Don't let me drown
I have stayed in your solar lights
Stayed so long that I'm too blind
Way too blind to see myself
Way too weak that I could tell
I have never felt a rain like this before
Never thought that I could drown in you
Stayed too long in your solar lights
Such a beautiful shade in a beautiful
Why don't you kill me?
Take a little more
Why don't you scream when I drown in you?
(Oh God I've) stayed too long in your solar lights
