In this letter, a novel patch crossover is proposed for the millimeter-wave signal distribution and routing applications. Great simplicity can be found both in design and structure because the symmetrical circular patch with several metallic posts loaded along the edge is employed as the core part of the crossover. It's well known that the standard crossover is usually implemented by cascading two...
In this paper, the structures and field emission properties of energetic C ion irradiated SiNWs have been investigated and influence of ion irradiation on structures and properties has been discussed. Vertically SiNW arrays are synthesized by using Ag-assisted electroless-chemical etching at room temperature, as reported in literatures. The process mainly comprises three steps: 1) surface cleaning...
In this paper, the investigation on the electron field emission enhancement from carbon nanotubes irradiated by energetic C ions are reported. Multiwalled carbon nanotube arrays (MW-CNTAs) are synthesized on (100) silicon substrates by a thermal chemical vapor deposition (TCVD) at 750°C for 30 min. In this procedure, a Fe thin film with a thickness of 5 nm is used as a catalyst, and the mixing of...
In this paper, a systematic procedure is presented to analyze and design a stable fuzzy controller for a class of nonlinear systems. Based on the Popov-Lyapunovpsilas method, the flight model is described with the expertpsilas linguistic information involved. The linguistic information for the flight model is represented as fuzzy sets. First, we transform a fuzzy control system into a flight control...
