    Biography

    Neil Trappe graduated with a B.Sc. in Applied Physics from the University of Limerick in 1998. He completed a Ph.D. in long wavelength optical analysis techniques in the Experimental Physics Department at NUI Maynooth in January 2002, before continuing to work in this research area as a Post-doctoral Research Associate until June 2003 on the HIFI instrument for the Herschel Space Observatory. Currently he is employed as a Senior Lecturer in the Experimental Physics Department, and has been working as First Year Course Co-ordinator. His research interests are in the field of far-infrared space optics. He has worked on the HIFI instrument for the European Space Agency’s Herschel Space Observatory (ESA PRODEX funded), Band 5 & 9 optical design for ALMA (SFI Research Frontiers funded) and currently is working on and managing a number of Technical Research Projects for the European Space Agency. This work is developing efficient analysis techniques, instrument design, and focal plane pixel architectures for future Cosmic Microwave Background space missions. He also recently obtained an SFI Infrastructure Award to establish a THz frequency measurement system.

    Research Interests

    Infrared Astronomy requires the detection of weak infrared radiation (heat energy) emitted from various interesting objects in the Universe. As every object with temperatures above absolute zero radiates even very cold objects glow emitting different types of EM radiation. Colder objects emit at longer wavelengths and so Far-Infrared Astronomy involves the study objects which are much too cool and faint to be detected with visible light. These include cool stars, infrared galaxies, clouds of particles around stars, nebulae, interstellar molecules, brown dwarfs and planets.

    We design, simulate and measure detection/receiver systems and telescopes for FarIR or Terahertz astronomy in the Experimental Physics Department at Maynooth University. We work on a number of international collaborations in this field.

    We have just completed an ESA funded contract "New Technology High Efficiency Horn Antennas for Cosmic Microwave Background Experiments and Far-Infrared Astronomy CCN1"
    In this research contract, we developed a number of different electromagnetic simulation tools targeting the development of focal plane detectors for future submillimetre astronomy and Cosmic Microwave Background (CMB) polarisation missions. We developed new technology solutions for the horn antenna feeds and detector coupling structures that can meet the technical requirements of the next generation of long-wavelength space missions building on the heritage and success of the Planck and Herschel Space Observatory missions. Based on modematching code techniques we have developed a number of modelling tools which incorporate coupling to free-space, lossy waveguides and numerous geometries that were previously difficult to model accurately. Many currently commercially available EM analysis software tools cannot be applied to large volume multimoded waveguide structures due to the computationally intensive nature of the problem. Usually each mode is analysed separately and this leads to many parallel simulations. Modematching allows all modes to be analysed simultaneously and so leads to a naturally computationally efficient approach. As we develop the code all required parameters can be extracted as desired.

    Analysis Tools developed

    • Optimization algorithms for single mode horn design
    • Multimoded waveguide analysis - includes
    • Absorbing sheets Cavity analysis 
    • Free space gap coupling 
    • Cylindrical and rectangular geometries  
    • Optical characterization & coupling

     

    W Band analysis of systematics

    • Deep Calibration & measurement
    • Modelling/Removal of multiple reflections
    • Waveguide probe design and analysis
    • Precise nearfield phase & amplitude
