Abstract
System, methods, and other embodiments described herein relate to a high-Q resonant state embedded system in a continuous body. In one embodiment, a system includes a longitudinally extending body that is subject to a flexural wave. The longitudinally extending body is attached to a fixed structure at a first end. The system also includes a mechanical resonator coupled to a surface of the longitudinally extending body along a length dimension of the longitudinally extending body. The mechanical resonator is located at a distance away from a second end of the longitudinally extending body to exhibit an infinite Q factor based on physical properties of the mechanical resonator.

A system, comprising:
- a longitudinally extending body that is subject to a flexural wave, the longitudinally extending body being attached to a fixed structure at a first end;
- and
- a mechanical resonator coupled to a surface of the longitudinally extending body along a length dimension of the longitudinally extending body, the mechanical resonator being mounted at a distance, based on physical properties of the mechanical resonator, away from a second end of the longitudinally extending body, wherein a Q factor of the mechanical resonator is maximized for the physical properties of the mechanical resonator.
A system, comprising:
- a longitudinally extending body that is subject to a flexural wave, the longitudinally extending body being attached to a fixed structure at a first end;
- and
- a mechanical resonator, comprising a rigid mass component, coupled to a surface of the longitudinally extending body along a length dimension of the longitudinally extending body, the mechanical resonator being mounted at a distance, based on a mass of the rigid mass component, away from a second end of the longitudinally extending body, wherein a Q factor of the mechanical resonator is maximized for the physical properties of the mechanical resonator.
A method, comprising:
- identifying physical properties of a mechanical resonator to be positioned along a length dimension of a longitudinally extending body that is subject to a flexural wave;
- identifying, based on the physical properties of the mechanical resonator, a distance away from a free end of the longitudinally extending body at which the mechanical resonator is to be affixed to maximize a Q factor of the mechanical resonator;
- and
- coupling the mechanical resonator to the longitudinally extending body at an identified distance from the free end.
