2. Spin-orbit coupling in transition metal systems : a study of octahedral Ni(II)
Abstract : The effects induced by spin-orbit coupling on the electronic states of Ni(II) complexes are studied with ab-initio and crystal field calculations.The ab-initio calculations are performed in two steps, to separate the coulomb and the spin-orbit effects. READ MORE

3. Infrared Emittance of Paper : Method Development, Measurements and Application
Abstract : Thermography is a non-destructive technique which uses infrared radiation to obtain the temperature distribution of an object. The technique is increasingly used in the pulp and paper industry. To convert the detected infrared radiation to a temperature, the emittance of the material must be known. READ MORE

4. Optical Studies of Periodic Microstructures in Polar Materials
Abstract : The optical properties of matter are determined by the coupling of the incident electromagnetic radiation to oscillators within the material. The oscillators can be electrons, ions or molecules. Close to a resonance the dielectric function exhibits strong dispersion and may be negative. READ MORE

5. Numerical Studies of Energy Gaps in Photonic Crystals
Abstract : The concept of photonic crystals was born in the late 1980's when two important letters were published that showed the possibility to control light propagation by a periodic structure. A photonic crystals consists of two or more materials with different dielectric functions periodically arranged on the length scale of light. READ MORE
