Lucyszyn S, Zhou Y, 2010, THz Applications for the Engineering Approach to Modelling Frequency Dispersion within Normal Metals at Room Temperature, PIERS Online, Vol: 6, Pages: 293-299
The use of the accurate classical relaxation-effect model for frequency dispersion innormal metals at room temperature with THz structures can be mathematically cumbersome andnot insightful. Recent work has demonstrated that it is possible to dramatically simplify otherwise complex analysis and allows for a much deeper insight to be gained into the classical relaxation-effect model. This paper gives applications for this engineering approach. Here, using the concept of Q-factor for a metal, the synthesized equivalent transmission line model is validated. Then, using the concept of complex skin depth, analysis is performed on hollow metal-pipe rectangular waveguides and their associated cavity resonators. This work proves that the mathematical modelling of THz structures can be greatly simplied by taking an electrical engineering approach to these electromagnetic problems.
Chrisostomidis CE, Lucyszyn S, 2010, Seed function combination selection for chained function filters, Vol: 5, Pages: 799-807
An algorithm is presented for seed function combination selection for chained function filters on the basis of pre-defined manufacturing limitations. To this end, and for the first time, combinatorial analysismethods have been applied to computer-aided filter design routines. A fundamental Monte-Carlo margin has been discovered that represents an upper-bound on the worst-case pass-band return-loss responses that cannot be exceeded. This can be exploited to extend the state-of-the art in tuningless high-performance filterimplementations towards higher frequencies and smaller fractional bandwidths or, alternatively, to lower the accuracy and manufacturing cost for a given set of filter specifications.
Zhou Y, Lucyszyn S, 2010, Modelling of reconfigurable terahertz integrated architecture (RETINA) SIW structures, PIER Journal, Vol: 105, Pages: 71-92
This paper discusses for the first time the combined optoelectronic-electromagnetic modelling of a new technology that represents a paradigm shift in the way millimetre-wave and terahertz electronics can be implemented using the REconfigurable Terahertz INtegrated Architecture (RETINA) concept. Instead of having traditional metal-pipe rectangular waveguide structures with metal sidewalls, RETINA structures have photo-induced virtual sidewalls within a high resistivity silicon substrate. This new class of substrate integrated waveguide (SIW) technology allows individual components to be made tuneable and subsystems to be reconfigurable, by changing light source patterns. Detailed optoelectronic modelling strategies for the generation of virtual sidewalls and their electromagnetic interactions are presented in detail for the first time. It is found with double-sided illuminated RETINA structures that an insertion loss of 1.3 dB/ λg at 300 GHz is predicted for the dominant TE10 mode and for a cavity resonator a Q-factor of 4 at 173 GHz is predicted for the TE101 mode. While predicted losses are currently greater than other non-tuneable/reconfigurable SIW technologies, there is a wide range of techniques that can improve their performance, while still allowing completely arbitrary topologies to be defined in the x-z plane. For this reason, it is believed that this technology could have a profound impact on the future of millimetre-wave and terahertz electronics. As a result, this paper could be of interest to research groups that have the specialised experimental resources to implement practical demonstrator exemplars.
