I'M JOEL LAMBERG
Researcher and Light Radiation Expert
Hi, I’m Joel Lamberg, and my journey into the world of light and electromagnetism began with my bachelor’s degree in electrical engineering. While I was originally drawn to electronics and its relation to sound waves, I quickly discovered a deeper fascination with how light behaves and the intricate beauty of electromagnetic fields. This led me to pursue a Ph.D. in Radio Science and Engineering, focusing on electromagnetism, where I could explore these phenomena in even greater detail.
During my time from bachelor's to Ph.D. studies at Aalto University, I’ve had the privilege of working on various projects, from optical force analysis to cornea imaging using terahertz frequencies. One of my most exciting experiences was working as an intern at NASA’s Jet Propulsion Laboratory in Los Angeles in 2023, where I designed broadband metasurfaces for advanced imaging systems. This experience deepened my understanding of how cutting-edge technology can push the boundaries of what we see and understand.
In addition to my hands-on work, I’ve developed my own theory on electromagnetic beam synthesis, which has been published in several peer-reviewed journals. These publications reflect my dedication to the rigorous science behind my art.
Today, my interest lies in enhancing metasurfaces to improve imaging systems, using my unique combination of scientific rigor and artistic vision. I’m driven by a desire to uncover the hidden beauty of light, whether it’s through academic research or the art I create.

Published Journals
Curved Boundary Integral Method for Electromagnetic Fields - Optics Express 2023
* Editor´s Pick *
The article presents the Curved Boundary Integral Method with comprehensive derivation and rigorous mathematical proofs. This study establishes a solid mathematical framework underpinning the theory. It explores the representations of electric and magnetic fields and confirms their precision through comparisons with analogous physical optics simulations.
Extended legality of Curved Boundary Integral Method - Optics Express 2023
The paper conducts a detailed analysis of beam synthesis using the Curved Boundary Integral Method at and around source points, providing evidence for the method’s validity across all spatial points. This research is deeply theoretical, establishing precise theorems that confirm the legitimacy of the electric and magnetic fields.
Advancing Curved Boundary Integral Method: Simplified Integral Solutions - Subm. IEEE AP-S 2024
The paper decreases the computational demands of the original Curved Boundary Integral Method. This reduction is achieved by simplifying two-dimensional integrations to one-dimensional using the cylindrical symmetry of Bessel functions. Consequently, electric and magnetic fields are represented through straightforward Bessel integrations, multiplied by constants that depend on position. This method effectively distinguishes between near and far-field components.
Mie scattering with 3D Angular Spectrum Method - Optics Express 2023
The paper develops the 3D Angular Spectrum Method from the Curved Boundary Integral Method. This transformation shifts the method’s focus from a source-based approach to one based on basis-function synthesis, enabling modeling of the beam propagation through surfaces. Additionally, this formulation facilitates the calculation of modified beam shape coefficients for vector spherical harmonic expansion, incorporating Mie theory.
Wavefront-modified vector beams for THz cornea spectroscopy - Optics Express 2023
The paper builds on previous articles' theories to enhance corneal spectroscopy's imaging capabilities. This enhancement involves the synthesis of wavefront-modified and polarization-optimized vector beams, along with an analysis of their scattering properties using a 100-layer spherical cornea model. Notably, the scattering behavior of spherical vector beams outperforms that of Gaussian beams, reducing the original analysis error of 5-10% to less than 0.1%. These improvements hold the potential for substantial clinical breakthroughs in detecting ocular diseases.
