% This code enables the analysis of nanolens menisus formed around the
% nanoparticle. A theoretical framework is provided in the following paper
% "Toward giga-pixel nanoscopy on a chip: a computational widefield look at
% the nano-scale without the use of lenses" and written by Ozcan et
% al. This paper can be found under the following link:

% The results from this code are presented and analysed in the following paper "Holographic Detection
% of Nanoparticles using Acoustically Actuated Nanolenses" and written by
% Aniruddha Ray, Muhammad Arslan Khalid, Andriejus Demcenko, Mustafa
% Daloglu, Derek Tseng, Julien Reboud, Jonathan Cooper, and Aydogan Ozcan,
% see Nature Communications 2019.

% The code is developed and implemented by M.A. Khalid and A. Demcenko 2017. The last check
% of this code was performed using Matlab R2018a on the 2nd December 2019.
% To run the code in Matlab, please, type start_elevation and press Enter.


Revisions:

% The code was revised on the 21st July 2021 by A. Demcenko using Matlab R2018a. 
% The revised code calculates results presented in Figure 7.
