TL;DR: A diffraction-based model to determine network link connectivity as a function of the locations of stationary and moving obstacles is developed and it is shown that multihop communication, with the introduction of a small number of relay nodes, is effective in maintaining network connectivity in scenarios where single-hop communication would suffer unacceptable outages.

TL;DR: In this article, active and nonlinear wave propagation devices for generation and detection of (sub)millimeter wave and (sub)-picosecond signals are described, including photodetectors with sampling circuits and instrumentation for millimeter-wave waveform and network (circuit) measurements both on-wafer and in free space.

TL;DR: Numerical results provide insight into the spatial variations of attainable capacity within a room, and the combinations of beamsteering and spatial multiplexing used in different scenarios are provided.

TL;DR: In this article, the authors reported the first observation of absolute negative conductance and multiphoton stimulated emission in sequential resonant tunneling semiconductor superlattices driven by intense terahertz electric fields.

TL;DR: In this article, the design of functional monolithic GaAs nonlinear transmission line (NLTL) is considered and the circuit design and diode design requirements for picosecond NLTL shock-wave generators and NLTL-driven sampling circuits are discussed.
