ARTIFICIAL MAGNETISM is the next theme, timely in that there has been a recent breakthrough on the subject from a Barcelona lab, a city close to my heart and full of innovative science. In addition, it is also applied to magnetic cloaking. In this field again, physicists have broken textbook paradigms with exciting new materials. Throw out all the old textbooks, time to start again.

DoD AND STEALTH TECH. "We plan to pursue prospects in the areas of open quantum systems, plasmonics, and transformation optics. Our results may be also applicable to ultrasonics where stealth properties are often desired." https://lnkd.in/b8aBttV View in LinkedIn

DoD AND STEALTH TECH. "We plan to explore a variety of opportunities provided by this reflection symmetry for a new generation of photonic materials, structures and devices that will exhibit novel optical properties and functionalities." https://lnkd.in/b8aBttV View in LinkedIn

DECLINING ABUNDANCE. "Half of the species assessed have shown strong changes in abundance or distribution, indicating that recent environmental changes are having a dramatic impact on the nature of the UK’s land and seas." https://lnkd.in/egeTAuK View in LinkedIn

TRAD STEALTH PLANES. "A stealth aircraft, on the other hand, is made up of completely flat surfaces and very sharp edges. When a radar signal hits a stealth plane, the signal reflects away at an angle. In addition, surfaces on a stealth aircraft can be treated so they absorb radar energy as well. https://lnkd.in/bWNFS7U View in LinkedIn

DECLINING ABUNDANCE. "We have quantitative assessments of the population or distribution trends of 3,148 species. Of these, 60% of species have declined over the last 50 years and 31% have declined strongly." https://lnkd.in/egeTAuK View in LinkedIn

CHIRALITY-SWITCHING DEVICE. "Based on transformation optics theory, we designed a chirality switching device, such that an object hidden inside would exhibit a reversed chirality (i.e., from left-handedness to right-handedness) for an observer at the far field." Not just a mirror image, but the original image is hidden. https://lnkd.in/bGA2Y3g View in LinkedIn

STATE OF NATURE REPORT UK (2013). "However, the report illustrates that targeted conservation has produced inspiring success stories and, with sufficient determination, resources and public support, we can turn the fortunes of our wildlife around." https://lnkd.in/egeTAuK View in LinkedIn

SPACE-TIME CLOAKS. "They are also exploring theoretical phenomena in hyperbolic metamaterials and photonic hypercrystals including subwavelength spatial solitons (ultranarrow beams of light that form due to self-focusing in nonlinear optical media) and space-time cloaks (that hide events in both specific places and times)." https://lnkd.in/ev_ZGjS View in LinkedIn

STATE OF NATURE REPORT UK (2013). "The report reveals that 60 per cent of the species studied have declined over recent decades. More than one in ten of all the species assessed are under threat of disappearing from our shores altogether." https://lnkd.in/egeTAuK View in LinkedIn
