Extended Composite Right/Left-Handed Transmission Line and Dual-Band Reactance Transformation
Journal of Electrical and Computer Engineering, 2010 An extended composite right/left-handed transmission line is introduced, and its dual-band bandpass filter characteristics are explored. Novel reactance transformations, derived from this transmission line, are formulated to transform a low-pass ...

An externally tunable bacterial band-pass filter [PDF]
Proceedings of the National Academy of Sciences, 2009 The current paradigm for tuning synthetic biological systems is through re-engineering system components. Biological systems designed with the inherent ability to be tuned by external stimuli will be more versatile. We engineered Escherichia coli cells to behave as an externally tunable band-pass filter for enzyme ...
