In 1973, and defended his Doctor of Philosophy thesis at Uppsala University in 1979. His Doctor of Philosophy was obtained under the supervision of professor Per Olof Fröman at the Department of Theoretical Physics, Uppsala University.
He received his Bachelor of Science in 1972, his Master of Science He has worked at the Swedish Institute of Space Physics in Uppsala since 1980, where he has been a professor since 2000. In 1981, Bo Thidé discovered electromagnetic emissions stimulated by powerful radio waves in the ionosphere during experiments in August 1981 at the EISCAT facility in Tromsø, Norway.\r\nForeign the first time it was shown that the plasma turbulence excited by powerful radio waves in the ionosphere radiates secondary electromagnetic radiation that can be detected and analysed on the ground.
These stimulated electromagnetic emissions (SEE) exhibit a rich spectral structure, particularly near harmonics of the ionospheric electron gyro frequency. The SEE technique is now a useful tool in plasma turbulence research.\r\nIn the mid-1980s, Thidé published a series of papers together with Bengt Lundborg on a highly accurate analytic approximation method to calculate the full three-dimensional wave pattern, spin angular momentum (polarization) and other properties of radio waves propagating in an inhomogeneous, magnetized, collisional plasma,\r\n Together with colleagues from Italy and Spain, Thidé discovered in 2010 a new phenomenon in General Relativity which allows the detection of spinning black holes by analysing the orbital angular momentum and optical vortex structure of radiation from the accretion disk near the black holes. The results were published in Nature Physics.
Thidé has advocated Orbital angular momentum multiplexing for radio transmissions, opening up additional degrees of freedom.\r\nThidé is the author of the book "Electromagnetic Field Theory", which is used in the course Classical Electrodynamics at Uppsala University and University of Padua.
