Biography

Dr Rair Macêdo is a theoretical physicist by training—but every so often dabbles in the world of experimental physics. He started pursuing research at the age of 16, as a part of his BSc studies, in the area of novel optical effects in natural hyperbolic media; and received a PhD in physics from the University of Glasgow in a similar area, but at an advanced theoretical level, modelling electromagnetic properties of magnetic structures. He has held a Leverhulme Trust Early Research Fellowship to develop novel metamaterials to control and manipulate electromagnetic waves and is currently a Lecturer in Electrodynamics and Spin Electronics at the Electronic & Nanoscale Engineering Division of the James Watt School of Engineering, University of Glasgow. 

Research interests

I study spins and spin systens as well as photonic, optic, magnetic and electromagnetic properties of matter.

My current research interests include:

  • Cavity Magnon-polariton quasiparticles (hybridisation between magnons and photons);
  • Metamaterials;
  • Magnetic media for signal processing devices;
  • Magnons-polaritons and optical properties of magnets;
  • Anisotropy in condensed matter as route to hyperbolic media; and
  • Novel optical effects including: Negative refraction, focusing by flat lenses, Goos-Hanchen shifts and nonreciprocity.

I am also currently working on ordering processes in a new class of frustrated and disordered systems called 'artificial spin ice', these include:

  • Spin ice systems; and
  • Liquid Crystals.

I am a member of the Quantum Circuits Laboratory.

Additional information

Public Engagement (advancing diversity, equity, and inclusion):

I currently serve as:

In order to help bridge the gap between science and disadvantaged groups, not only social and financial, but also racial, sexual orientation, gender and any other minority group, I developed a series of high school activities, including seminars and demonstrations, which I delivered to schools in rural and remote areas of South America this last summer.

These activities target children at an early age when they are just starting to study scientific subjects such as physics, chemistry and biology.  My main focus was to motivate children from an underprivileged background to get into STEM and I worked with over 150 children.

School_I

The overarching goal of these initiatives was to help reduce barriers in education or research in science for underrepresented and/or economically disadvantaged groups.

I am now working on incorporating these ideas at the University of Glasgow as outreach activities for the greater Glasgow area community.
