Chartres Cathedral rosette pendant with resonant cavities

Description

Inspired by an 800 year old shape

I am designing here an antenna inspired by a spiritual motif that was drawn 800 years ago on a disc 10 cm in diameter. This disc has two sides that are identical. We can find the circular lobed shapes in the maze pattern. Learn more 

A contemporary form, the magnetron

This resonant cavity shape has been used since 1940 in the design of the magnetron.
The magnetron is a device that transforms the kinetic energy of electrons into electromagnetic energy, in the form of microwaves. The electrons are emitted at the center and are deflected in a spiral path in the resonant cavities.
This technology is used in radars and household microwaves.

Resonating and amplifying cavities

The parallel between the magnetron and the forms composing the rosette seems to show us that we have here a form made to amplify what will cross it. This shape is present in most cathedrals. We also find inside the domes located on the ceilings, acoustic cavities acting here also as resonators.

Passive use

You can place the disc next to you or on one of the meridian or chakra points that you want to stimulate. You can energize water or enhance wine by placing the disc under the liquid. Use it also to keep your fruit longer.
