Classical electrodynamics is the first field theory students usually encounter. Let us just take a look what kind of impact the discovery of Maxwell's equations had on science.

A new implementation of static caching provides photonics101.com with ultra-fast page loads.

The iFDTD is a software made for fast and easy electrodynamic simulations. Its biggest strength lies in the visualization of electrodynamic effects like total internal reflection, light propagation in photonic crystals etc.

Graphene is a two-dimensional material with extraordinary properties. Its tunable conductivity makes the material a prime candidate for sophisticated light-matter interactions. We will see how graphene antennas can be used to dictate a molecule's emission frequencies.

With the freely available interactive FDTD toolbox you can simulate and visualize the electromagnetic field in a structured material such as a photonic crystals, waveguides or investigate refraction at dielectric boundaries and diffraction in free space.

In this second tutorial we will show how to define a refractive index profile n(r) within the interactive FDTD toolbox. We will simulate the total internal reflection in a glass prism using a Gaussian shaped beam.

In the third tutorial of the interactive FDTD toolbox we will simulate the light propagation inside a photonic crystal. We will see that it will be very intuitive to understand the reflection at a defect and the use of a photonic crystal as beam splitter.

In this first tutorial we want to demonstrate the effects of perfectly matched layer boundary conditions and get to know the interactive FDTD toolbox.

Before we can all admire the new and exciting green future, let us have a clear and analytic look on what the disadvantages of solar energy are. Let us also find out what these disadvantages mean practically.

Resistors, capacitors and inductors are the basic passive elements of any electric circuit. Find out why resistors are so important, how we may describe and characterize them and what materials they are made off!
