As another example of the reduction in the number of runs, consider an experiment to investigate three design and four environmental variables, all at three levels. A Taguchi crossed array might use a 3 fractional factorial design for the design array and a 3 fractional factorial design... 

Having considered the advantages of designing an experiment with a combined set of design and environmental variables, as opposed to Taguchi s crossed arrays, this section will consider the analysis of such experiments. 

The crossed array designs have two important properties, related to the methods of analysis described above. First, these designs enable independent estimation of all design by noise factor interactions that is, interactions involving one design factor and one noise factor (Shoemaker et al., 1991). Thus they are well suited to the response model analysis. Second, they provide a fair comparison of the design factor combinations, by subjecting them to identical noise conditions. 

For background correction and cross-array normalization, VSN was performed. You may also choose RMA for the processing of the raw data [6, 7]. 

An important group of nanoantennas are those based on the Babinet principle. A metal shape surrounded by dielectric and a dielectric-filled hole in metal with identical shape and size have identical diliiaction patterns. Thus bowtie shaped holes in metal can be used, two holes are a Babinet equivalent of a nanodimer, arrays of nanoholes are equivalent of arrays of nanoparticles, crossed arrays of nanoholes correspond to crossed arrays of nanoparticles, etc. [318].

Cross array hot wire method (BS EN 993-14 1998 and ISO 8894-1 1987) — In this method, two wires are welded together and sandwiched between the blocks of the test material. One is a heater, and the other is a thermocouple, and they lie in as cross arrangement. Hence the name. Power is fed to the hot wire for a short time, and the temperature rise measured. The temperature rise is related to the thermal conductivity of the material. This arrangement is more suited to measurement of materials with conductivities up to 2 W/mK.
