In this paper, we discuss and analyze the criteria for the existence and the generation of surface modes in dielectric slabs with and without metallic layers (frequency selective structures, FSS). The material parameter of the slab is in general bianisotropic, but the examples and the numerical computations show only isotropic materials. It is shown that there are three different categories of reso

Calculations of the one-electron Green's function give a single-particle spectrum where, besides the usual quasi-particles, a new peak of appreciable strength appears which corresponds to an electron coupled to real plasmons.

Popular Abstract in Swedish I avhandlingen jämförs påföljdsbestämningen i Sverige och straffutmålingen i Norge eftersom det allmänt anses att det är olika straffteorier som motiverar svensk och norsk straffrätt. Dels systematiseras, analyseras och tolkas svensk och norsk lagstiftning samt förarbeten, dels jämförs rättsfall från 1996 och 1997 från Högsta domstolen och Höyesterett. Frågeställningar The thesis is concerned with the penal theories. The general opinion is that it is neoclassicism that mainly motivates sentencing in Sweden but not in Norway. The penal theories concerning sentencing in Norway is supposed to be a combination of theories between general deterrence and special deterrence with elements of retribution. If this is the case this should be evident from a comparison betwe

This paper explores the issue of private retail governance to deliver SCP. In particular it focuses on the role of private retail eco-brands to promote sustainability both upstream and downstream in the food supply chain. The analysis and discussion centers around the question whether private retail eco-brands are better fitted to introduce sustainability into the food supply-chain than 3rd party

Popular Abstract in Swedish Stora mängder reaktiva lågmolekylära ämnen används i den kemiska industrin vid produktionen av varor som hanteras i vårt dagliga liv. Exempel på sådana kemikalier är organiska syraanhydrider (OAA). En stor andel av de arbetare som exponeras för dessa viktiga industriella föreningar blir tyvärr sjuka med symtom som astma och hösnuveliknande besvär. I åtminstone en del faOrganic acid anhydrides (OAAs) are important industrial chemicals but also potent inducers of airways diseases. Many exposed workers develop specific IgE and IgG antibodies. Hexahydrophthalic anhydride (HHPA) and methylhexahydrophthalic anhydride (MHHPA) are two particularly sensitising OAAs. The aim of this thesis was to develop and evaluate a method for biological monitoring of exposure to and r

The purpose of this contribution is twofold. First, we revisit the longitudinal component (also referred to as common-mode component, asymmetric component or antenna-mode component) occurring at the receive side of a twisted-pair loop. Second, we propose a simple setup for RFI tests that captures reality more accurately than performing differential-mode and common-mode tests separately. In essence
