2. 1. Transient Electromagnetic Waves in Nonlinear Media

   Author : Daniel Sjöberg; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signal processing; nonlinear materials; Electromagnetic waves; instantaneous response; waveguides; shock waves; entropy condition; Elektronik och elektroteknik; Electronics and Electrical technology; Signalbehandling; Electromagnetism; optics; acoustics; Elektromagnetism; optik; akustik;

   Abstract : This thesis is concerned with the propagation of transient electromagnetic waves in nonlinear media. It consists of a General Introduction and five scientific papers. The General Introduction gives a broad overview of nonlinear electromagnetic phenomena. READ MORE

4. 2. Radiant Textiles : Designing electromagnetic textile systems

   Author : Erin Lewis; Tincuta Heinzel; Högskolan i Borås; []
   Keywords : HUMANIORA; HUMANITIES; smart textiles; electromagnetism; textile design; design methods; artistic research; Textiles and Fashion Design ; Textil och mode konstnärlig ;

   Abstract : To regard the electromagnetic domain of conductive textiles is to unlock a realm of expressive possibilities. The underexplored area of the electromagnetic domain in con­ductive textiles implies that numerous computational and electronic textiles created thus far possess untapped capabilities. READ MORE

5. 3. Radiant Textiles : A framework for designing with electromagnetic phenomena

   Author : Erin Lewis; Delia Dumitrescu; Katharina Bredies; Högskolan i Borås; []
   Keywords : HUMANIORA; HUMANITIES; smart textiles; interaction design; textile interaction; textile; electronic; electromagnetism electromagnetic; design methods; artistic research; Textiles and Fashion Design ; Textil och mode konstnärlig ;

   Abstract : The design of smart, interactive, computational, and electronic textiles involves working with unknown variables that expand the tangible dimensions of textiles. Non-visual concepts such as electromagnetic fields, electrical current, computational code, and the temporal attributes of materials that exhibit dynamic qualities require that textile designers be able to perceive and manipulate domains of the textile that extend beyond its conventional forms of expression.

6. 4. Space Plasma Dynamics : Instabilities, Coherent Vortices and Covariant Parametrization

   Author : David Sundkvist; Jan-Erik Wahlund; Andris Vaivads; Stuart Bale; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Space and plasma physics; space physics; plasma; instabilities; turbulence; coherent structures; vortex; self-organization; magnetosphere; waves; electromagnetism; covariant; space instrumentation; Rymd- och plasmafysik; Space physics; Rymdfysik;

   Abstract : The magnetospheric cusps are two funnel-like regions of Earth's magnetosphere where solar wind plasma can have direct access to the ionosphere. The cusps are very dynamic regions where wave-particle interactions continuously take place and redistribute energy among different particle populations. READ MORE

7. 5. Effective properties of heterogeneous materials with applications in electromagnetics

   Author : Christian Engström; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; homogenization; optics; acoustics; Electromagnetism; structural parameters; anisotropic material; inverse homogenization; Bloch waves; Maxwell s equations; Elektromagnetism; optik; akustik; Inverse bounds;

   Abstract : Composite materials, i.e, mixtures of two or more materials, are commonly used in industry, because they often have outstanding properties in comparison with the original materials. In many cases the inhomogeneities are on a very fine scale, which makes it difficult to perform a full numerical simulation of the material. READ MORE
