  1. 1. Nonlinear materials for optical power limiting characterization and modelling

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Hampus Lundén; Linköpings universitet.; Linköpings universitet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : High power laser pulses can be a threat to optical sensors, including the human eye. Traditionally this threat has been alleviated by colour filters that block radiation in chosen wavelength ranges. READ MORE

  2. 2. Nonlinear Microwave Measurement Architectures for Wideband Device Characterization

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Sebastian Gustafsson; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nonlinear characterization; wideband; GaN HEMT; oscilloscope; microwave; active load-pull;

    Abstract : The global surge for ubiquitous mobile communication requiring high speed and high capacity cellular networks has resulted in a golden age for the development of wireless technology. Modern cellular standards employ complex modulation formats with wider signal bandwidths to cope with the growing demand. READ MORE

  3. 3. Methods for Simulation and Characterization of Nonlinear Mechanical Structures

    University dissertation from Karlskrona : Blekinge Institute of Technology

    Author : Martin Magnevall; Blekinge Tekniska Högskola.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear dynamics; nonlinear parameter estimation; harmonic balance; reverse-path; zero-memory nonlinear systems; hysteretic nonlinearities; dry-friction; geometric nonlinearities;

    Abstract : Trial and error and the use of highly time-consuming methods are often necessary for modeling, simulating and characterizing nonlinear dynamical systems. However, for the rather common special case when a nonlinear system has linear relations between many of its degrees of freedom there are particularly interesting opportunities for more efficient approaches.

  4. 4. Short Pulses in Engineered Nonlinear Media

    University dissertation from Stockholm : KTH

    Author : Stefan Holmgren; KTH.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nonlinear optics; KTiOPO4; frequency conversion; mode-locked lasers; ultra-fast lasers; visible lasers; short pulses; ultrafast nonlinear optics; diagnostic applications of nonlinear optics; nonlinear optical materials; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik;

    Abstract : Short optical pulses and engineered nonlinear media is a powerful combination. Mode locked pulses exhibit high peak powers and short pulse duration and the engineered ferro-electric KTiOPO4 facilitates several different nonlinear processes. READ MORE

  5. 5. Simulation and Experimental Methods for Characterization of Nonlinear Mechanical Systems

    University dissertation from Karlskrona : Blekinge Institute of Technology
