Papadopoulos A, Anderson J, Kim E, Mavridis M, Isliker H
Entropy (Basel)
. 2023 Jun;
25(6).
PMID: 37372286
A geometrical method for assessing stochastic processes in plasma turbulence is investigated in this study. The thermodynamic length methodology allows using a Riemannian metric on the phase space; thus, distances...

Appl Opt
. 2018 Sep;
57(25):7303-7313.
PMID: 30182992
Several known and widely used averaging techniques aiming to improve the accuracy of the two-dimensional finite-difference frequency-domain (FDFD) method, in the presence of material discontinuities, are reviewed, numerically tested, and...

Papadopoulos A, Glytsis E
Appl Opt
. 2012 Dec;
51(35):8460-9.
PMID: 23262543
Preferential input-waveguide grating couplers are rigorously analyzed using the pseudospectral time-domain method in the total field/scattered field formulation for TE and TM polarizations in conjunction with the convolutional perfect matching...

Papadopoulos A, Glytsis E
Appl Opt
. 2010 Oct;
49(30):5787-98.
PMID: 20962943
We rigorously analyze and compare preferential-order waveguide grating output couplers using the finite-difference time-domain method in the total-field/scattered-field formulation for TE and TM polarizations. Four kinds of preferential-order grating couplers...

Papadopoulos A, Glytsis E
Appl Opt
. 2009 Sep;
48(27):5164-75.
PMID: 19767934
Output optical waveguide grating couplers are rigorously analyzed using the 2-order and the 4-order finite-difference time-domain (FDTD) method in conjunction with the total field/scattered field (TF-SF) approach and special averaging...

Appl Opt
. 2008 Apr;
47(12):1981-94.
PMID: 18425170
The total-field-scattered-field formulation of the finite-difference time-domain method (FDTD) is used to analyze the diffraction of finite incident beams by finite-number-of-periods holographic and surface-relief gratings. Both second-order and fourth-order FDTD...
