Revealing Invisible Scattering Poles via Complex Frequency Excitations
Deepanshu Trivedi, Arjuna Madanayake, Alex Krasnok
Recent research in light scattering has prompted a re-evaluation of complex quantities, particularly in the context of complex frequency signals, which exhibit exponential growth o…
Anomalies in Light Scattering: A Circuit Model Approach
Deepanshu Trivedi, Arjuna Madanayake, Alex Krasnok
In experimental physics, it is essential to understand electromagnetic (EM) wave scattering across EM spectrum, from radio waves to X-rays, and is pivotal in driving photonics inno…
Fano-Qubits for Quantum Devices with Enhanced Isolation and Bandwidth
Deepanshu Trivedi, Leonid Belostotski, Arjuna Madanayake +1
Magneto-optical isolators and circulators have been widely used to safeguard quantum devices from reflections and noise in the readout stage. However, these devices have limited ba…
Low-Complexity Loeffler DCT Approximations for Image and Video Coding
D. F. G. Coelho, R. J. Cintra, F. M. Bayer +6
This paper introduced a matrix parametrization method based on the Loeffler discrete cosine transform (DCT) algorithm. As a result, a new class of eight-point DCT approximations wa…
Fast Radix-32 Approximate DFTs for 1024-Beam Digital RF Beamforming
A. Madanayake, R. J. Cintra, N. Akram +6
The discrete Fourier transform (DFT) is widely employed for multi-beam digital beamforming. The DFT can be efficiently implemented through the use of fast Fourier transform (FFT) a…
Energy-efficient 8-point DCT Approximations: Theory and Hardware Architectures
R. J. Cintra, F. M. Bayer, V. A. Coutinho +2
Due to its remarkable energy compaction properties, the discrete cosine transform (DCT) is employed in a multitude of compression standards, such as JPEG and H.265/HEVC. Several lo…
