During the corrugated board making process the board is passing several rollers and belts, which compress the material more or less. This also happens later in the process when corrugated board sheets are printed, scored and die-cut. As a damage trouble shooting tool, thickness measurements are not sensitive enough to estimate the amount of crushing in these processes. The loss in thickness wil...

A novel idea of conformal corrugated edges (CCE) is put forward in this paper for tapered slot antennas to obtain improved low-frequency characteristics. The CCE is realized using conformal slots whose two longitudinal boundary lines are modelled using curvilinear function of the curves that form the tapered slots. So the conformal slots can sufficiently corrugate edges of the tapered slot ante...

We consider the relative stability of parallel and perpendicular lamellar layers on corrugated surfaces. The model can be applied to smectic phases of liquid crystals, to lamellar phases of shortchain amphiphiles and to lamellar phases of long-chain block copolymers. The corrugated surface is modelled by having a single q-mode lateral corrugation of a certain height. The lamellae deform close t...

We propose a method to synthesize several band-rejection filters by etching split-ring resonators (SRRs) on the transmission line for spoof surface plasmon polaritons (SPPs), which is made of double-side or single-side corrugated metal strips. From dispersion relations, the corrugated strips can support spoof SPP modes when the operating frequency is less than the cutoff frequency. The electric...

Spectral field measurements were used to quantify the ultraviolet (UV) spectral albedos of four different metallic roofing surfaces. The effect of the albedos of two of these surfaces on erythemal exposure to human facial anatomical sites was quantified by UV dosimetry. The albedos of all roofing surfaces were greater than the albedo of grass. Little SZA dependence was observed for any of the s...

Goods that are shipped world-wide travel protected by packages that are frequently made of corrugated board. Therefore, the strength of corrugated board containers is crucial for preserving the content, while an optimization of corrugated board containers is essential to save money and resources. Unfortunately, standard compression tests show a wide dispersion in container performance, and so, ...
