Groupthink

Groupthink

When in group settings, we are often influenced by the thoughts, feelings, and behaviors around us. Groupthink is another phenomenon of conformity where modification of the opinions of members in a group aligns with what they believe is the group consensus (Janis, 1972). In such situations, the group often takes action that individuals would not perform outside the group setting because groups make more extreme decisions than individuals do. Moreover, groupthink can hinder opposing trains of...

Area of Science:

Physics
Materials Science
Thermal Engineering

Background:

Natural mirages rely on air density gradients.
Metamaterials enable artificial optical illusions but face challenges with exotic parameters and object signature alteration.
Current illusions cannot fully conceal an object's presence due to single virtual signatures.

Purpose of the Study:

To address limitations in artificial optical illusions by developing thermal illusion thermotics.
To propose a general design paradigm for thermal illusion metadevices.
To achieve simultaneous manipulation of heat sources, including moving, shaping, rotating, and splitting.

Main Methods:

Designing thermal metadevices to manipulate thermal conduction.
Utilizing a specific setup for illusion thermotics.
Developing a general paradigm for creating thermal illusions.

Main Results:

Successfully mimicked exterior thermal behavior of a reference object.
Split an interior heat source into multiple virtual signatures.
Demonstrated the ability to mislead awareness of heat source location, shape, size, and number through temperature profiles.

Conclusions:

The proposed thermal illusion thermotics overcome limitations of existing optical illusions.
The developed metadevices offer robust control over heat sources, enabling complex thermal manipulation.
This concept holds potential for advancements in optics, electromagnetics, and other physical fields for multi-functional illusions.
