European sovereignty between autonomy and dependence: a guide for EU policy
Published 2023“…But today its relevance appears uncertain in the face of Russia’s invasion of Ukraine and the growing assertiveness of China. This brief argues that European sovereignty (and related concepts such as strategic autonomy) is still an important and necessary guide for EU policy, but only if it is dissociated from some of the excessive and overambitious definitions given to the concept when it was first developed.…”

Design of microstrip ultra wide band antenna with two notch filters for wireless communication
Published 2015“…In order to add reconfigurable characteristics to the patch antenna, two copper strips are putted on the slots to represent the ON and OFF switching status of an ideal Pin diode. By using this simple switching technique, the current distribution of the patch changes and enables the antenna to have four modes of operation. …”

Tetraazamacrocyclic ligands and their copper complexes
Published 1982“…For the 15-membered macrocycle, 18,19,20,21-tetrahydro-17-H-tribenzo(f,j,n)(1,5,9,12)tetraazacyclopentadecine, derivatives bearing different substituents in one of the benzene rings were prepared. For the diimine ligands of this type both cationic and neutral copper(II) complexes were isolated and characterised; (the latter type result from loss of anilino protons on complex formation.) …”
