|January 4, 2024
Summary
Researchers developed new cloaking strategies based on ideal-lens cloaks. These "shifty cloaks" image interior objects to the outside, with a paraxial shifty cloak experimentally realized.
Area of Science:
- Optics
- Metamaterials
- Transformation Optics
Background:
- Ideal-lens cloaks are theoretical constructs.
- Previous work explored shifty cloaks and devices using transformation optics.
- Cloaking strategies aim to render objects undetectable.
Purpose of the Study:
- To connect novel cloaking strategies to existing research on shifty devices.
- To investigate new combinations of shifty cloaks, Janus devices, and optical wormholes.
- To experimentally realize a paraxial shifty cloak.
Main Methods:
- Utilizing principles of transformation optics.
- Combining shifty cloaks with Janus devices and optical wormholes.
- Experimental fabrication and testing of a paraxial shifty cloak.
Main Results:
- Demonstrated experimental realization of a paraxial shifty cloak.
- Connected novel cloaking strategies to established shifty device research.
- Investigated theoretical combinations of cloaking devices.
Conclusions:
- The presented cloaking strategies are closer to experimental realization.
- The study advances the understanding and application of shifty cloaks.
- Novel combinations of cloaking devices show potential for future research.

The arrangement of electrons in the orbitals of an atom is called its electron configuration. We describe an electron configuration with a symbol that contains three pieces of information:

01:01Weightlessness
5.0K
When an object is dropped, it accelerates toward the center of the Earth. If the net external force on the object is its weight, it is said to be in free fall; that is, the only force acting on the object is gravity. Galileo was instrumental in showing that, in the absence of air resistance, all objects fall with the same acceleration g. However, when objects on the Earth fall downward, they are never truly in free fall, because there is always some upward resistance force from the air acting...

2.2K
Although black holes were theoretically postulated in the 1920s, they remained outside the domain of observational astronomy until the 1970s.
Their closest cousins are neutron stars, which are composed almost entirely of neutrons packed against each other, making them extremely dense. A neutron star has the same mass as the Sun but its diameter is only a few kilometers. Therefore, the escape velocity from their surface is close to the speed of light.

01:05Total Internal Reflection Fluorescence Microscopy
5.8K
Total internal reflection fluorescence microscopy or TIRF is an advanced microscopic technique used to visualize fluorophores in samples close to a solid surface with a higher refractive index, such as a glass coverslip. TIRF only allows fluorophores in proximity to the solid surface to be excited. When light from a medium with a lower refractive index (such as air) hits the glass coverslip at a critical angle, the light undergoes total internal reflection stead of passing through the glass.

02:32The de Broglie Wavelength
25.9K
In the macroscopic world, objects that are large enough to be seen by the naked eye follow the rules of classical physics. A billiard ball moving on a table will behave like a particle; it will continue traveling in a straight line unless it collides with another ball, or it is acted on by some other force, such as friction. The ball has a well-defined position and velocity or well-defined momentum, p = mv, which is defined by mass m and velocity v at any given moment. This is the typical...

Consider a plane wavefront traveling in position x-direction with a constant speed. This wavefront can be utilized to obtain the relationship between electric and magnetic fields with the help of Faraday's law.
