  1. 1. Efficient Methods to Calculate Mutual Coupling between Generic Antennas on Large Platforms

    Author : Johan Malmström; B. Lars G. Jonsson; Lars Pettersson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis presents research on methods for calculating the mutual coupling between antennas. The mutual coupling between antennas is a measure of the amount of energy transmitted from one antenna that is received by another, and is a key parameter when installing antennas on platforms, such as aircraft.

  3. 3. Local Structure of Hydrogen-Bonded Liquids

    Author : Matteo Cavalleri; Lars G.M. Pettersson; John Tse; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hydrogen-bond; water; ice; density functional theory; DFT; core-level spectroscopies; x-ray absorption; Physical chemistry; Fysikalisk kemi;

    Abstract : Ordinary yet unique, water is the substance on which life is based. Water seems, at first sight, to be a very simple molecule, consisting of two hydrogen atoms attached to one oxygen. READ MORE

  4. 4. Structure Modeling with X-ray Absorption and Reverse Monte Carlo: Applications to Water

    Author : Mikael Leetmaa; Lars G M Pettersson; John Rehr; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; water structure; x-ray absorption; spectroscopy; diffraction; reverse monte carlo; XAS; EXAFS; XANES; RMC; TP-DFT spectrum calculations; Physics; Fysik; kemisk fysik; Chemical Physics;

    Abstract : Water is an important substance. It is part of us, of our environment, and is a fundamental prerequisite for the existence of life as we know it. The structure of water is still, after over 100 years of research on the subject, however under debate. READ MORE

  5. 5. Le Fantôme de l’Opéra - Studies on Atoms and Electrons Beneath

    Author : Chang Liu; Lars G. M. Pettersson; Anders Nilsson; Anders Hellman; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Carbon dioxide reduction; Subsurface oxygen; X-ray spectroscopy; Density functional theory; CO desorption; teoretisk fysik; Theoretical Physics;

    Abstract : The carbon dioxide reduction reaction is a promising candidate to tackle ecological challenges of our age. This is due to its capability of reducing carbon dioxide emission generated from the combustion of fossil fuels by converting carbon dioxide into valuable hydrocarbons. READ MORE
