Despite emphasising ‘urban’ as signifier, cities conceptualized as “dense networks of interwoven sociospatial processes that are simulta

A priori estimates on the partial realized gain of UWB-antennas

A summation rule valid for a large class of linear and reciprocal antennas is presented in terms of the electric and magnetic polarizability dyadics. The identity is based on the holomorphic properties of the forward scattering dyadic and includes arbitrary shaped antennas modeled by linear and time-translational invariant constitutive relations. In particular, a priori estimates on the partial re
