Abstract: A single turn, asymmetric solenoidal coil for imaging the hand and wrist of a human subject. The asymmetric shape of the coil allows for uniform RF field energy to be distributed along the hand and wrist of the subject. The shape of the coil is maintained by a hollow, elongated member of dielectric material. A complementary pair of foils are attached to the outer surface of the hollow, dielectric member. The foils are separated by axial gaps and electrically coupled to each other by capacitors disposed along the length of each gap.

Abstract: A wireless server-to-server datacenter network architecture uses wireless links to eliminate the need for power-hungry switching fabric of traditional fat-tree based datacenter networks. The server-to-server wireless datacenter network (S2S-WiDCN) requires Line-of-Sight (LoS) between servers to establish direct communication links. Utilizing this LoS links, a horizontal-first routing algorithm is developed which, will establish fast communication links between any pair of communicating servers in the data center. The wireless links can be realized in millimeter-wave (such as 30, 60, 120 GHz) or THz (such as 300 GHz) frequency bands. The use of antenna-arrays to create beam-steering towards communicating servers is necessary to establish the direct server-to-server links. In the presence of an obstruction such as an IT technician, the LoS between communicating servers may be blocked. To address this issue, an obstruction-aware adaptive routing algorithm for the S2S-WiDCN is proposed. Alternatively, the wireless links can be realized with FSO. The performance of such a wireless data center is better than that of conventional tree-based wired data centers while its power consumption is significantly lower than that of the conventional data center network.
