A compact 60‐GHz on‐chip bandpass filter in GaAs technology
Electronics Letters, Volume 60, Issue 7, April 2024.A compact 60‐GHz on‐chip bandpass filter (BPF) is presented using gallium arsenide (GaAs) technology. The measurements show that it has a centre frequency of 60.2 GHz with a bandwidth of 14%, and the minimum insertion loss (IL) within the passband is 2.57 dB. The chip size, excluding the feedings, is about 0.265 mm × 0.184 mm. Abstract A compact 60‐GHz

Survey of Connectivity Restoration in 3D Wireless Ad Hoc/Sensor Networks
International Journal of Distributed Sensor Networks, Volume 2024, Issue 1, 2024.Wireless ad hoc/sensor networks (WASN) have seen increased application in three‐dimensional (3D) environments, such as underwater and aerial scenarios. However, WASN may be fragmented or unable to connect continuously due to the harsh surrounding environment or high mobility.

Nonlinear transmission lines for pulse shaping in silicon [PDF]
, 2005 Nonlinear transmission lines (NLTL) are used for pulse shaping. We developed the theory of pulse propagation through the NLTL. The problem of a wide pulse degenerating into multiple pulses rather than a single pulse is solved by using a gradually scaled ...
