Subject: Can household microwave be tuned to such a frequency that it resonates H2O

I AM CURRENTLY UNDERTAKING A PROJECT THAT REQUIRES THE EFFICIENT 
REMOVAL OF WATER FROM SUBSTANCES. I WOULD LIKE TO USE A 
MICROWAVE BUT I'M NOT REALLY SURE HOW A MICROWAVE WORKS, I THINK 
IT OPERATES AT A NUMBER OF FREQUENCIES ONE I HOPE RESONATES 
WATER. THE QUESTIONS I NEED ANSWERED INCLUDE: WHAT IS THE BASIC 
OPERATING PRINCIPLE OF A HOUSE HOLD MICROWAVE, WHAT IS THE 
RESONANT FREQUENCY OF WATER AND IS IT POSSIBLE TO TUNE A HOUSE 
HOLD MICROWAVE TO RESONATE WATER ONLY. ANY HELP YOU CAN PROVIDE 
WOULD BE VERY MUCH APPRECIATED.
CHEERS, GREG F
