  Micromegas detector is considered to be a promising candidate for a large
variety of high-rate experiments. Micromegas of various geometries have already
been established as appropriate for these experiments for their performances in
terms of gas gain uniformity, energy and space point resolution, and their
capability to efficiently pave large read-out surfaces with minimum dead zone.
The present work investigates the effect of spacers on different detector
characteristics of Micromegas detectors having various amplification gaps and
mesh hole pitches. Numerical simulation has been used as a tool of exploration
to evaluate the effect of such dielectric material on detector performance.
Some of the important and fundamental characteristics such as electron
transparency, gain and signal of the Micromegas detector have been estimated.
