ieeetran
How can I add a subtitle to my Latex document using the IEEETran document class?
I would like to know if it is possible to use a built-in command that gives me the regular title in addition to a subtitle written in a slightly smaller font?
I found this question related to it, where they recommend to use a title page, but this does not seem to fit my needs. Also, I looked in the documentation for the IEEETran class but was unable to find it there.
The big problem with your idea is the way, LaTeX is building the page.
If you have two colums on the page, LaTeX has to calculate it. You want to end the "two column mode", change to one column to add your footnote or footnotes. There are a lot of things influencing the result, like the length of the paragraphs, the length of the footnotes, that causes an changing of the length of the column etc. That is not easy to calculate!
If you argue but there is the possibilty to have an abstract in one column please see that the situation is an other there. It is much more easier to insert an box for the complete textwidth at the beginning than at the end.
My english is not so good, so please have a look for example to this question and see the accepted answer. perhaps it is today possible, to do the recalculation with expl3 as mentiond by Frank Mittelbach, but I can't do that.
So I suggest you to use the following MWE to get hyphenated urls placed in the column they belong to:
\documentclass[10pt,conference,a4paper,twocolumn]{IEEEtran}
\usepackage{showframe} % <======================== shows the typing area
\usepackage{blindtext} % <========================= to create blind text
\usepackage[hyphens]{url} % <================ allows hyphenating of urls
\usepackage[colorlinks,urlcolor=blue]{hyperref}
\begin{document}
\Blindtext
Some random text\footnote{\url{
http://ec.europa.eu/digital-agenda/interoperability-standardisation-connecting-ehealth-services}}
\Blindtext
Some random text\footnote{\url{
http://ec.europa.eu/digital-agenda/interoperability-standardisation-connecting-ehealth-services}}
\Blindtext
\end{document}
and the resulting first page:
showing clickable blue urls.
Class IEEEtran defines and uses macros \@IEEEheaderstyle and \@IEEEfooterstyle for the font setup of headers and footers. The definitions depend on the option settings, from IEEEtran.cls:
% set up the running headers and footers
%
% header and footer font and size specifications
\def\@IEEEheaderstyle{\normalfont\scriptsize}
\def\@IEEEfooterstyle{\normalfont\scriptsize}
%
% compsoc uses sans-serif headers and footers
\ifCLASSOPTIONcompsoc
\def\@IEEEheaderstyle{\normalfont\sffamily\scriptsize}
\def\@IEEEfooterstyle{\normalfont\sffamily\scriptsize}
\fi
The macros can be redefined to use a larger font than \scriptsize, e.g.:
\def\@IEEEheaderstyle{\normalfont\small}
\def\@IEEEfooterstyle{\normalfont\small}

You could do something like this.
