Dive summary:

• A group of physicists has a suggestion for engineers for a way to, in effect, drain off energy that vibrates at a frequency that could lead to a collapse.
• It's unusual for a bridge to encounter wind or other natural energy that pulses at just the right rate to generate sympathetic vibrations in a bridge and cause it to collapse, as everyone who has taken physics has seen in film of the Tacoma Narrows Bridge in 1940, or be closed for safety reason, as happened in England in 2000 and Russia in 2011.
• The physicists' solution is a series of cubic structures bolted beneath a bridge deck, connected by bars to each other and to the bridge and "tuned" in their design to soak up energy that would be harmful to the particular bridge where they are installed.

Michele Brun, Alexander Movchan, Ian Jones and Ross McPhedran describe a "wave bypass" technique that has many similarities to those being used by researchers looking to create Harry Potter-style invisibility cloaks....
