We explore the use of a hybrid and networked system for medical applications. In particular we are interested in monitoring the physiological data of newborn babies. The key element in our design is the use of cell phones as aggregating devices for the sensor collected information. Cell phones in particular enable secure communications with medical wireless sensors. We discuss a key distribution scheme among mobile cell phones and stationary networks of medical sensors. Our goal is to isolate and limit the security damages when nodes of a given sensor network are compromised. We show with simulation results the offered tradeoffs among security, connectivity and node memory.

Plasmonic modulator antennas have been recentlyshown to be able to efficiently upmix millimeter and THz waves onto optical frequencies. In this paper, we introduce a theory and equivalent circuit models for designing and optimizing plasmonic modulator antennas. The proposed model aims to improve the overall understanding of the experimentally found powerful antenna field enhancement (between the impinging field at the antenna and the field within the modulator). This enhancement has already been shown to be as high as 90'000 and allows to efficiently evaluate relevant figures of merit for antenna design and optimization. The effects of antenna design parameters are presented and discussed in detail. The accuracy of the suggested models is verified by rigorous numerical computation through field simulations. As a result, we propose optimized antenna structures and their parameters, and demonstrate their field enhancement capabilities.
