For a monopole antenna (a), the Earth acts as a ground plane to reflect radio waves directed downwards, making them seem to come from a virtual "image antenna" (b).In Telecommunications, a ground plane is a flat or nearly flat horizontal conducting surface that serves as part of an antenna, to reflect the radio waves from the other antenna elements.
The figure ground plan organizes the primary urban landscape components - plots, streets, constructed spaces, and open spaces [8] – into a diagram of solid and void; the proportions, of which, can be manipulated to create different urban morphologies. If building mass (solid poche) is greater than open space (void), spatial continuity is ...
Free design of the ground plan – commonly considered the focal point of the Five Points, with its construction dictating new architectural frameworks. [4] The absence of load-bearing partition walls affords greater flexibility in design and use of living spaces; the house is unrestrained in its internal use.

A key discovery was the existence of groups of homeobox genes, which function as switches responsible for laying down the basic body plan in animals. The homeobox genes are remarkably conserved between species as diverse as the fruit fly and humans, the basic segmented pattern of the worm or fruit fly being the origin of the segmented spine in ...
A rotunda (from Latin rotundus) is any roofed building with a circular ground plan, and sometimes covered by a dome. It may also refer to a round room within a building (a famous example being the one below the dome of the United States Capitol in Washington, D.C.). The Pantheon in Rome is perhaps the most famous, and is the most influential ...
A floor plan is not a top view or bird's-eye view; it is a measured drawing to scale of the layout of a floor in a building. A top view or bird's-eye view does not show an orthogonally projected plane cut at the typical four foot height above the floor level. A floor plan may show any of the following elements: [3] interior walls and hallways ...
On sites with little stratigraphic depth, a pre-excavation multi-context plan is sometimes made of all visible features before any excavation is carried out. This helps in planning strategy since problems of stratigraphy on rural sites are minimal as features often cut into the natural minimizing issues of inter-cutting features .
