Provided is a reflection-type bandpass filter for ultra-wideband wireless data communication. The junction member and the filter are situated between a reference electrolyte solution and a sample solution. In some embodiments, the system tracks influence, and in some embodiments, a console provides vision into various information provided by the system. In one embodiment, each respective one of the segments is to be selectively switched on or off to adjust a phase of the optical beam. By using the overall effective space-time channel after coherent combining rather than before coherent combining, the complexity and correspondingly the resources required for obtaining the orthogonal sub-channels is significantly reduced. The processes involve adding a relatively small but effective amount of the ionic gum before a fermentation step, preferably prior to initial homogenizationheating steps, to provide ionic gum-dairy protein interaction without causing coacervation with protein.
