Using Bloch waves to represent the full solution of Maxwell’s equations in periodic media, we study the limit where the material’s period becomes much smaller than the wavelength. It is seen that for steady-state fields, only a few of the Bloch waves contribute to the full solution. Effective material parameters can be explicitly represented in terms of dyadic products of the mean values of the non

Popular Abstract in Swedish Many of the energy needs in today’s modern society are fulfilled by sources based on fossil fuels, including non-domestic oil and coal. It is well known that the increase in CO2 emission is the result of human activities, mostly fossil fuel consumption. The use of such fuels is unsustainable and has led to the phenomena such as climate change, political instability in sThe gasification of biomass is a promising route to increase the share of renewable sources in the energy mix. Besides having an overall higher thermal efficiency than combustion, it also offers the possibility of producing gaseous and liquid biofuels that can be used in the transport sector. The use of biomass gasification for energy purposes can help lower the net emissions of greenhouse gases,
