2. 1. Intentional electromagnetic interference (IEMI) : Susceptibility investigations and classification of civilian systems and equipment

   Author : Daniel Månsson; Rajeev Thottappillil; Mats Bäckström; William Radasky; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electromagnetic compatibility; Intentional electromagnetic interference; High power electromagnetic; Other engineering physics; Övrig teknisk fysik;

   Abstract : This PhD thesis addresses the threat posed to society by sources that can produce high power electromagnetic pulses (HEPM) and be used maliciously to disturb or damage electronic equipment. The vulnerability from intentional electromagnetic interference (IEMI) has increased in the recent decades due to the widespread dependence of the civil society on sensitive electronic systems and proliferation of radiation sources.

4. 2. Inversion and Joint Inversion of Electromagnetic and Potential Field Data

   Author : Jochen Kamm; Ari Tryggvason; Laust B Pedersen; Mehrdad Bastani; Douglas Oldenburg; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inversion; Electromagnetic methods; Joint inversion; Potential Field methods; Inversion; Elektromagnetische Verfahren; Joint-Inversion; Potentialverfahren; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

   Abstract : In this thesis, four inversion problems of different scale and difficulty are solved. Two of them are electromagnetic inverse problems. Two more are joint inversion problems of potential field data and other types of data. READ MORE

5. 3. Electromagnetic Waves in Media with Ferromagnetic Losses

   Author : Jörgen Ramprecht; Martin Norgren; Constantin Simovski; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrophysics; Elektrofysik;

   Abstract : The operation of a wide variety of applications in today's modern society are heavily dependent on the magnetic properties of ferromagnetic materials and their interaction with electromagnetic fields. The understanding of these interactions and the associated loss mechanisms is therefore crucial for the improvement and future development of such applications. READ MORE

6. 4. Occupational exposure to electromagnetic fields and chronic diseases

   Author : Niclas Håkansson; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Electromagnetic fields; chronic diseases; epidemiology; occupation; cancer diseases; neurodegenerative diseases; cardiovascular diseases.;

   Abstract : This thesis consider two exposures from the electromagnetic spectrum extremely low-frequency magnetic fields (ELF MF) and ultraviolet (UV) radiation. ELF MF are the lowest and UV radiation ranges among the highest frequencies of non-ionizing radiation. The exposure prevalence of these fields is high in the general population. READ MORE

7. 5. Transient electromagnetic pulse propagation in temporally dispersive materials

   Author : Igor Egorov; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Green functions; direct scattering; time domain; wave propagation; bi-gyrotropic; chiral; bi-isotropic; Forerunner; precursor; Green dyadics; Electronics and Electrical technology; Elektronik och elektroteknik;

   Abstract : This thesis treats the problem of transient electromagnetic pulse propagation in temporally dispersive media. The analysis is performed using time-domain techniques. In particular, the dispersive wave splitting which decouples the Maxwell equations both in vacuum and inside the medium is utilized. READ MORE
