Unsing string for indexing though structures

Hey, I would like to create a while loop with which I can read mat files one after the other and evaluate them automatically without writing a separate program for each mat file. Loading the mat files works using the loop, but unfortunately I can't access the structures with a variable s2.
Does someone have a solution for it?
i = 108;
% A = ((0.1255)/2)^2*pi;
% ml_in_m3 = 1e-6;
while i <= 108
pfad = '...';
s = strcat(pfad,'Test3_',string(i),'.mat');
s2 = strcat('Test3_',string(i));
load(s);
figure(2)
plot(s2.X.Data,s2.Y(8).Data)
t = s2.X.Data;
y = s2.Y(8).Data;
x = 0:0.001:s2.X.Data(end);
y=interp1(t,y,x,'spline');
i = i+1;
end
%the error that occur is: Unrecognized method, property, or field 'X' for class 'string'.

% s2 = strcat('Test3_',string(i));
s2 = load(s); % <--changed here
figure(2)
plot(s2.X.Data,s2.Y(8).Data)
t = s2.X.Data;
y = s2.Y(8).Data;
x = 0:0.001:s2.X.Data(end);
y=interp1(t,y,x,'spline');
i = i+1;
end

hey, thank you for the answer, but this doesnt work. I tried it, but than s2 is an struct with the form s2.Test3_... Than i have still the Problem to loop through the diffenrent names
Do all mat files have same variable names?
yeah, only the name of the file and the values of the variables are changing
