Yesterday I had faced the same problem. This morning, I found out that the filename was too long. I changed it shorter.
From:
\includegraphics[scale=0.35]{Pictures/Fig1_Theory_Map1.png}
into:
\includegraphics[scale=0.35]{Pictures/Fig1_Theory1.png}
It has been solved now.
One can avoid the problem by using the \footnotemark
-\footnotetext
mechanism:
\begin{column}{0.4\textwidth}
\begin{itemize}
\item Discretization of both space and time by central differences.
\item Yee Cell\footnotemark
\end{itemize}
\end{column}
\footcitetext{Taflove2000}
However this poses another problem: the text of the footnote may go over the navigation symbols, so another adjustment suggested by lockstep is needed (see this answer): the following code should go in the preamble
\addtobeamertemplate{footnote}{\vspace{-6pt}\advance\hsize-0.5cm}{\vspace{6pt}}
\makeatletter
% Alternative A: footnote rule
\renewcommand*{\footnoterule}{\kern -3pt \hrule \@width 2in \kern 8.6pt}
% Alternative B: no footnote rule
% \renewcommand*{\footnoterule}{\kern 6pt}
\makeatother
Choose your pick. I've modified the code adding also something for reducing the text width for the footnotes, or they will go all the way to the margin.
There are some errors in your .bib
entry:
@Book{Taflove2000,
Day = {30},
Edition = {2nd},
Month = {jun},
Publisher = {Artech House Publishers},
author = {Taflove, Allen and Hagness, Susan C.},
title = {{Computational Electrodynamics: The Finite-Difference Time-Domain Method}},
year = {2000},
}
Too many braces: Biber and biblatex are not able to understand properly the data.
Best Answer
beamer
supports floats, but doesn't make them float as it does not help or make sense within a presentation. So, drop the float specifier[t]
. Additionally, thefigure*
environment is meant to used in atwocolumn
setup that is not natively supported inbeamer
. So, usefigure
instead.Furthermore, there is no need to use a
figure
environment if you just want to place an image. For that you can just use\includegraphics[.]{..}
. However, if you must, you can usefigure
with a\caption
.Note how
beamer
doesn't print a number with the\caption
within afigure
. That's because it's better to repeat a figure than to refer to it much later in the presentation using a number. Consider your audience when using references and perhaps consider using\againframe
(if needed).
