Abracadabra: Making Things Invisible and Seeing the Unseen

Invisibility cloak anyone? This months Science Cafe is presented by LRSM lab at UPenn on using meta-materials to play with light.

Talk starts at 6, but lets meet early to grab good seats and get a bit to eat/drink from the HH menu.

How can we make an object invisible? When a wave hits an object, it scatters, and that splashing of waves is how we can see that object. What if we design a structure that cloaks an object, i.e., it channels an incoming wave around it, without being scattered so we don't see that object? Metamaterials and nanotechnology may provide recipes for such interesting possibilities. Conversely, there are features of light that our eyes cannot see. Can we build cameras that make these features detectable, allowing us to make invisible things visible?

    Good turnout today. Thanks to the 17 from the two groups who showed up. Using special materials and structures to make things microwave invisible and inversely making things that are normally invisible such as angle if polarization visible. Glad he took the time after the event to provide details.

    I'm tentative for this right now, but I am interested in the topic.
