  We filled a void with a regular or asymmetric pattern without overlap using a
time-dependent packing method termed random sequential adsorption (RSA). In the
infinite-time limit, the density of coverage frequently hits a limit. This
study focused on the saturation packing of squares and their dimers, trimers,
tetramers, pentamers, and hexamers, all of which were orientated in two
randomly chosen orientations (vertical and horizontal). Our results concurred
with those of previous extrapolation-based research1. We used the "separating
axis theorem" to detect if freshly added polygons and previously put ones
overlapped. When RSA insertion became disproportionately sluggish, we concluded
that saturation had been attained. We also discovered that the system's
capacity to fill the area decreased as squares were stretched into dimers and
trimmers. The microstructure of the resultant saturation was also thoroughly
investigated, including block function and the structural arrangement of dimers
and trimers. Based on results of ref2, it is predicted that layer adsorbed onto
a substrate will not hinder diffusion. Moreover, it was found that the adsorbed
rectangles' aspect ratio had an impact on the coverage percentage at the
jamming limit, with aspect ratios of 2 (like dimers here) producing the highest
jamming coverage. As a result, the current results are a more in-depth
expansion of the report in reference3.
