Wave plate

is an optical component that delays the light polarized parallel to its slow axis relative to light polarized parallel to its fast axis by an amount proportional to the refractive index difference along the two directions and the thickness of the plate, and inversely proportional to the wavelength of the

The light shined through the thin hotel blinds to wake up the newly wedded couple on their romantic honeymoon. The beautiful tropical sky was cloudless with a never ending blue skyline. The turquoise water went on for miles in the horizon. As Mike open the blinds the glistening sun had blinded him. His beautiful wife laying in their king size been with the covers covering her scandalous body. Her blue eyes slowly opened as she gazed at Mike. The glimmer in her eyes made it clear that he was her true

is switched to my brother’s favourite show, but he’s not in here. “Moo moo, where are you?” No response once again. That’s odd? Things have been a little strange lately. There’ve been big trucks driving up and down our street. They have no number plates or anything on their car. I think I’ve seen them a few times before at our other houses, but before this week, I hadn’t seen them here. Mum says for me not to worry about them as they aren’t my problem. But lately when I’ve asked, her voice wavers

Optimizing the Performance of a Standing Wave Loudspeaker Driven Thermoacoustic Refrigerator Alamir, M.A., Elnegiry, E.A., Eltahan, H.R. Abstract— This study investigates the design and optimization steps of a thermoacoustic refrigerator. Matlab code will be used for optimizing the stack length and its position. DeltaEC version 6.3b11 will be used to do the code used for simulating the refrigerator to identify the optimized operating conditions such as the frequency, the mean pressure and the oscillating

fundamental mode can be excited in such a wavelength rectangular cavity, providing out of phase radiation from radiating edge of patch. A sub wavelength resonance tuned at desired frequency while gain of radiator is expected to be very poor. The parallel plate cavity showed analogus limitation there are no degree of freedom in selecting the desired operating mode in sub wavelength regime of operation. A circular patch antenna loaded by a grounded inhomogeneous substrate with thickness h ,consisting of a

This report investigates resonance phenomena of driven damped simple harmonic oscillations by measuring accelerations and frequencies of an oscillator. Since it turned out that oscillations with low damping have smaller errors than those with high damping, small damping cases are employed to examine the resonance phenomena. Based on the Newton's 2nd Law \cite{book}, the motion of oscillations can be modeled by the following differential equation and its solution. \begin{equation} \label{eq1} \ddot

beauty that seemed to be hidden until I experienced the ocean for myself. We were an hour into our trip when I started to hear the sound of laughing water. I looked out towards a big wave that dad and little brother battled through. My heart jumped at the sight of the wave, rolling in towards me. I heard the hissing of waves inching closer to my kayak. I looked towards the side of my kayak, leaning myself far over the side. My kayak tipped over into the ocean (Crossing the first threshold).The cold water

the motion of a piece. As a cellist for over six years, I wanted to understand the fundamental idea of why notes were audible. I asked myself, why do I press down on certain parts of the strings on a cello to produce certain notes? How are sound waves calculated? With these two questions in mind, I dove in with the desire to apply a different perspective of music. Diagram 1 One of the earliest discoveries of how string function comes from the Greek philosopher, Pythagoras. The wavelength and

discussed. Simulation is done in MATLAB software and results are obtained. Keywords— Dynamic voltage restorer, voltage sag, sensitive load I. INTRODUCTION Power system make sure good quality of electrical power supply which means voltage and current wave form should be balance and sinusoidal. Moreover, the voltage level on the system should be within dependable limit, generally within 100+ -5% of their rated value if the voltage is more or less than this pre-specified value, performance of equipments

Cloaking Soumay Gupta1 and Tanvi Sharma1 14116067 14116070 1 E&C Department, Indian Institute of Technology Roorkee Abstract Metamaterials have been a subject of increasing interest due to their ability to manipulate the flow of EM waves. We analyse the mechanism by which metamaterials are able to exhibit this property which is exploited to develop the Harry Potter-esque invisibility cloaks. We briefly discuss the whole new branch of optics called “Transformation
