A barrier/seed system for electroless metallization on complex surfaces using (aminomethylaminoethyl)phenethyltrimethoxysilane self-assembled films
Jeremy K . L. Peters, Garon D. Ashby, Hans D. Hallen
High frequency signals propagate along the edges of conductors. If the conductors are electroplated, then the seed layer forms at least one edge, so care must be taken to insure th…

Early Warning of mmWave Signal Blockage and AoA Transition Using sub-6 GHz Observations
Ziad Ali, Alexandra Duel-Hallen, Hans Hallen
The susceptibility of millimeter-wave (mmWave) signals to physical blockage and abrupt signal strength variations presents a challenge to reliable 5G communication. This work propo…
