Botswana has been depicted as an African success story having the highest long-run growth rates over the last four decades since independence combined with a stable multi-party democratic system. In this paper the success story is critically investigated and analysed from a structural perspective. The question is posed if Botswana's success truly is a case of economic development as opposed to gro
Frequency dependence of the permittivity and permeability is inevitable in metamaterial applications such as cloaking and perfect lenses. In this paper, Herglotz functions are used as a tool to construct sum rules from which we derive physical bounds suited for metamaterial applications, where the material parameters are often designed to be negative or near zero in the frequency band of interest.
